The Hexagon Rotary Broach Kit (often called a “wobble broach”) is the ultimate solution for machining blind or through-hexagonal holes directly on your lathe, milling machine, or CNC turning center. Instead of transferring a part to a slotter or EDM, you can generate precision hex sockets in seconds.
Versatile Mounting: Available in a wide variety of mounting options to fit any machine in your shop, including Morse Tapers (MT2, MT3, MT4).
The “Wobble” Action: The tool body is engineered with a precise 1-degree offset spindle. As the tool feeds into the workpiece, this offset creates a cutting action where only one corner of the broach is cutting at a time. This drastically reduces the required thrust force, preventing damage to your machine’s spindle or tailstock.
Premium Japanese Bearings: At the heart of this rotary broach are ultra-smooth Japanese bearings, ensuring the broach freely synchronizes with the rotation of the workpiece under heavy thrust loads.
Complete HSS Cutter Set: This kit isn’t just the holder—it comes completely ready to run with six High-Speed Steel (HSS) hex broaches (3mm, 4mm, 5mm, 6mm, 8mm, and 10mm). These cutters feature a standard 12mm shank and effortlessly slice through aluminum, brass, and steel up to 35 HRC.
Manufactured in Vietnam This tooling is manufactured to high standards in Vietnam, combining heavy-duty, high-grade steel bodies with premium internal Japanese bearings. It is an incredibly cost-effective way for smaller job shops and hobbyists to bring rotary broaching in-house without spending thousands on a Swiss-made equivalent.
Over 30 units sold to my Australian Customers with great reviews and feedback. Some customer feedback about the cutters easily working with hardened steel and lasting, I’ve not had any orders for replacement cutters.
The SK 40mm Setting Ring is a precision ground bore reference standard used to calibrate and zero internal measuring instruments. Whether you’re setting a bore gauge, checking a plug gauge, or establishing a known internal diameter reference on the bench, this ring gives you a traceable, repeatable datum to work from. At 40mm nominal diameter with a deviation of -0.0001mm from nominal, this is a toolroom-grade reference — not a workshop approximation.
Precision ground internal bore to 40mm nominal (-0.0001mm deviation) — That sub-micron deviation figure means you’re setting your bore gauge or internal micrometer against a reference that’s accurate well inside one tenth of a thou. Your measurements are only as good as your reference; this ring gives you a solid one.
Hardened steel construction with knurled OD — The knurled outer diameter isn’t decorative — it prevents the ring rolling off the bench and gives a secure grip when handling with oily hands. The hardened bore resists wear and maintains geometry through repeated use, which is critical for a setting standard that needs to hold its size over time.
Clearly engraved nominal size and deviation markings — The face is engraved with 呼40 (nominal 40mm) and the actual deviation (-0.0001mm), so there’s no guesswork about what you’re working to. In a busy toolroom where multiple rings might be in circulation, clear marking prevents costly mix-ups.
Compatibility — Suits any internal bore gauge, three-point bore micrometer, or air gauge calibrated for the 40mm range. No adaptor or accessory required — just clean the bore, present your instrument, and zero off the ring. Pairs with dial bore gauges, Mitutoyo or similar 3-point internal micrometers, and plug gauge setting equipment.
Ideal for — Zeroing dial bore gauges before measuring cylinder bores, bearing housings, and hydraulic cylinder bores; setting three-point internal micrometers for tight-tolerance shaft and bore fits; verifying bore gauge accuracy on surface grinders and cylindrical grinding setups; and as a go/no-go reference when checking bored-out workpieces on the lathe or mill.
Condition
Used (Good Condition / Previously Used, Stored Correctly)
The bore — the only surface that actually matters on a setting ring — presents well. The internal diameter shows no visible damage, scoring, or raised burrs that would compromise the reference surface. The flat faces and knurled OD carry the typical light patina and minor surface marks consistent with a used toolroom gauge that’s been handled and stored over time; there is some surface oxidation and light staining visible on the flat face as shown in the photographs, but this is cosmetic only and does not affect the precision ground bore. The ring has been lubricated and wrapped in plastic for storage and shipping — correct practice for preserving a ground bore standard. As with any used setting ring, best practice before putting it into service is to verify the internal diameter against a calibrated internal micrometer or reference gauge at your site; the engraved deviation (-0.0001mm) reflects the original factory calibration and should be treated as a reference point pending your own verification. There is no case included, however the ring is supplied clean, lubricated, and wrapped for transit.

Brand Information
SK (Soko Measuring Instruments) is a well-regarded Japanese metrology brand with a long history of producing hardened and ground gauging tools for toolroom and production environments. Made in Japan, SK products sit comfortably alongside RSK and Niigata as respected mid-to-upper tier Japanese gauge manufacturers — a tier below Mitutoyo in terms of global distribution, but entirely comparable in terms of ground surface quality and dimensional accuracy for setting rings and reference standards. Japanese-made gauging tools carry a strong reputation in Australian toolrooms for consistent quality and long service life, and the “Made in Japan” mark on this ring is a meaningful indicator of manufacturing standard.

The Mitutoyo QuantuMike 293-141-30 is a 25–50mm digital outside micrometer built for toolroom-grade measurement where speed and accuracy aren’t negotiable. Featuring Mitutoyo’s high-speed spindle mechanism — four times faster than a conventional thimble — the QuantuMike gets you to your reading quickly without sacrificing the 0.001mm resolution and IP65 coolant-proof protection that make it a credible production floor instrument. This is a metre-range mic that earns its place on the bench next to a surface plate, not just in a drawer.
High-speed spindle (4× standard advance rate) — The QuantuMike’s spindle advances at approximately 3.2mm per thimble revolution rather than the conventional 0.5mm. In practice, this means less time winding down to your workpiece and more time cutting chips. Particularly valuable when checking a run of turned parts where you’re opening and closing the mic dozens of times a shift.
IP65 coolant-proof rating — Sealed against coolant splash, swarf, and workshop grime. A standard digital mic can fail progressively when exposed to water-soluble coolant; the IP65 housing on this instrument protects the encoder and electronics at the machine rather than requiring you to walk back to a dry bench before measuring.
0.001mm resolution with ABS/INC and HOLD functions — Absolute (ABS) origin memory means the mic retains its zero reference after the battery is changed or the power cycles, which eliminates the common frustration of re-zeroing on a setting standard mid-job. The HOLD function locks the display for measuring in awkward positions — useful when checking bore depths or internal shoulders where you can’t read the display in situ.
Setting standard included — The 25mm setting standard (gauge block-grade reference cylinder) allows you to verify and set the instrument’s zero before use. Without a traceable reference, even a mechanically perfect mic is just a number generator. Having this in the kit means you can calibrate against a known ground reference without sourcing a separate standard.
Ideal for — Checking turned shaft diameters and shoulder widths on the lathe, verifying ground stock and precision bar to size before setup, incoming inspection of purchased components, four-jaw chuck and steady rest setup on a manual lathe, and first-article inspection of CNC-turned parts in the 25–50mm range.
Condition
(Used — Good Condition / Pre-owned, functionally sound)
The micrometer presents in good used condition consistent with careful workshop service. The anvil and spindle faces — the two surfaces that directly determine measurement accuracy — show no visible pitting, grooving, or deformation; the critical contact surfaces appear clean and flat. The frame carries light surface patina and minor handling marks typical of a bench instrument that has seen regular use, but there is no structural damage, cracking, or distortion to the frame or thimble. The digital display functions clearly, the ORIGIN, ZERO/ABS, and HOLD buttons are all responsive, and the spindle advances and retracts smoothly with no detectable slop or drag in the barrel. The IP65 sealing appears intact with no visible damage to the housing seams.
As with any used precision instrument, verification against the included setting standard before putting it into production use is strongly recommended. Zero the mic on the 25mm setting standard, confirm the display reads within ±0.002mm, and check for repeatable closure across three or four cycles on the standard to confirm spindle and ratchet consistency. If you require a current NATA-traceable calibration certificate, that is not included and would need to be arranged independently — however, for the vast majority of toolroom and production applications, self-verification against the setting standard is entirely appropriate.

The Mitutoyo 177-146 is a 50mm precision setting ring gauge — a hardened, ground reference standard used to zero and verify bore measuring instruments before they go anywhere near a job. At 50.004mm internal diameter, this ring gives you a certified reference point for setting bore gauges, air gauges, and internal micrometers so your first measurement on the part is one you can actually trust.
Hardened and precision-ground bore — 50.004mm certified internal diameter: The bore surface is lapped to a mirror finish and held to tight tolerances, giving you a stable, repeatable reference that won’t drift between uses. The 0.004mm offset from nominal is common in Mitutoyo’s setting ring series and is clearly marked — always account for it when zeroing your instrument.
Robust, thermally stable construction: The ring is manufactured from hardened steel, which resists wear at the reference surface over thousands of setting cycles. Thermal stability matters here — if you’re working in a temperature-controlled toolroom or waiting for parts to stabilise before measuring, a hardened steel ring behaves predictably.
Protective outer jacket / grip ring: The cream-coloured polymer outer sleeve visible in the image isn’t decorative — it acts as a thermal barrier, slowing heat transfer from your hand to the ring body so skin temperature doesn’t introduce dimensional error during use. It also makes the ring easier to handle without scratching the reference bore on the bench.
Compatibility: Designed for use with Mitutoyo bore gauges, internal micrometers, air gauging systems, and any other bore-measuring instrument requiring a 50mm setting master. No additional accessories are required to use the ring itself.
Ideal for: Zeroing two-point or three-point bore gauges before checking cylinder bores, bearing housings, hydraulic block bores, or bush fits; verifying internal micrometre zero on 50mm range instruments; setting air gauging plugs on production lines; and confirming bore gauge repeatability during toolroom calibration routines.
Condition
Used (Good Condition / Toolroom Pulled)
The reference bore is in good functional condition — the lapped internal surface shows no visible scoring, pitting, or damage to the measuring surface. The hardened bore retains its ground finish and is free from the kind of wear or contact marks that would compromise its use as a setting reference. The outer polymer grip sleeve shows age-related discolouration consistent with normal bench use — this is purely cosmetic and has no effect whatsoever on the ring’s dimensional performance. The engraved markings (50.004mm, model number 177-146, serial 040623) are clean and fully legible. As with any used setting master, we recommend verifying the ring against a calibrated reference or CMM before committing it to critical production work, particularly if traceability documentation is required for your QMS. For toolroom, maintenance, or high-quality hobby shop use, this ring is entirely fit for purpose as presented.

1 x Mitutoyo Setting Ring 177-146 — 50.004mm internal diameter
1 x Protective carry case / pouch
Not included: Calibration certificate or NATA traceable documentation.
Brand Information
Mitutoyo is Japan’s largest manufacturer of precision measuring instruments and one of the most respected names in metrology worldwide — sitting at the top tier of the market alongside Mahr, Tesa, and Starrett. Founded in 1934 and headquartered in Kawasaki, Japan, Mitutoyo manufactures everything from handheld verniers to coordinate measuring machines, and their toolroom-grade gauging products are used as reference standards in aerospace, automotive, and defence manufacturing globally. Japanese-made Mitutoyo instruments are widely regarded as the benchmark for value, accuracy, and long-term reliability in the Australian toolroom market.
When you need to measure more than the typical 10mm travel of a standard dial gauge, the Mitutoyo 3058F steps in without compromise. With a full 80mm measuring range on a 58mm diameter dial, this long-stroke indicator is built for deep-bore runout checks, tall workpiece deflection surveys, and any setup where a short-travel gauge simply won’t cover the ground. Japanese-made, Mitutoyo-precise, and presented here in a condition that punches well above its used price point.
80mm measuring range, 0.01mm graduation: Most workshop dial gauges top out at 10mm travel — fine for tramming and runout, but useless for checking long-stroke spindles, tall castings, or multi-pass stock surveys. The 3058F gives you 80mm of calibrated travel in a single instrument, eliminating the need to reset or swap gauges mid-check.
Dual-scale face with revolution counter: The large outer dial reads in 0.01mm increments across a full 100-division scale, while the inner revolution counter tracks cumulative travel across the full 80mm range. On long-stroke checks you always know exactly where you are — no mental arithmetic trying to count full rotations of the main hand.
Balanced dial bezel with friction lock: The rotating bezel lets you zero the dial against any reference surface quickly, and the friction-fit holds position under vibration — important when the gauge is mounted on a mag base on a running machine for in-process checks.
8mm stem (standard toolroom shank): The 8mm stem is the universal fitment for dial indicator holders, mag bases, surface gauge arms, and most indicator stands in Australian workshops. No adapters needed for the vast majority of setups.
Ideal for: Checking ram or quill travel on drill presses and mills, surveying flatness across long surfaces on a surface plate, setting up steady rests on long-bed lathes, measuring total deflection in fixture and jig assemblies, and any transfer-type measurement where a short-travel gauge would need resetting multiple times.
Condition
(Used — Like New / Stored, Minimal Use, if any)
The gauge itself presents exceptionally well, potentially new, just with dust. The crystal is clear and unmarked, the dial face is clean with no discolouration or staining, and the bezel rotates smoothly with consistent friction throughout its travel. The stem and contact point show no sign of side-loading or impact — both precision surfaces are free of burrs, scoring, or measurable wear. Spindle travel is smooth and consistent across the full 80mm stroke with no stiction or hesitation, and the hand returns crisply to zero with no evidence of rack or gear wear. The knurled stem lock and bezel lock function as intended.
The outer packaging carries the honest marks of a decade on the shelf — the box shows fade, corner wear, surface scuffing, and general storage patina consistent with its age. That’s the box, not the gauge. Inside, the polystyrene insert is intact and holds the gauge, papers, and sealed accessory pack tightly and correctly. The accessories remain in their original sealed bag, and the documentation is crisp. This is a tool that was boxed up and stored correctly rather than bounced around a workshop for ten years.
Given the storage period, we recommend a straightforward verification before committing it to critical work: zero the gauge against a known reference or master setting ring and check for consistent return-to-zero across several strokes at the start, middle, and end of the travel range. This is standard practice for any precision instrument returning to active service, and based on the condition observed here, it is expected to verify cleanly.
Not included: No separate magnetic base or indicator stand is included. The gauge is supplied as pictured with the accessories shown.
Brand Information
Mitutoyo Corporation, founded in Japan in 1934, is the global benchmark in precision metrology — the name against which every other measuring instrument manufacturer is measured, not the other way around. Their gauges, micrometers, and CMM equipment are found in aerospace, automotive, and defence toolrooms worldwide precisely because Mitutoyo holds their manufacturing tolerances and calibration traceability to a standard that most competitors treat as aspirational. Within the precision instrument market, Mitutoyo sits at the top tier alongside Mahr and Tesa, a clear step above mid-tier brands and a world away from generic imports. For a working machinist or toolmaker, a Mitutoyo instrument is a known quantity: buy it once, calibrate it once, trust it for decades.

The Ocean D454 Setting Ring is a 32mm bore gauge master ring — a hardened, precision-ground reference standard used to set bore micrometers, internal dial gauges, and telescoping gauge setups to a known diameter before you go near the workpiece. Marked ø32 with a deviation of –0.001mm, this ring gives you a traceable starting point that keeps your internal measurements honest. It’s the kind of toolroom reference that sits next to your Mitutoyo bore mic and doesn’t leave the bench.
Precision-ground bore to ø32mm (–0.001mm deviation) — the engraved tolerance tells you exactly where this ring sits relative to nominal, so you can account for it when zeroing your instrument rather than chasing phantom error in your workpiece.
Hardened steel construction — setting rings take a lot of contact from gauge anvils and bore mic measuring faces. A hardened bore resists wear at the reference surface, meaning the ring holds its geometry over thousands of uses without the bore going bell-mouthed or out-of-round.
Knurled outer diameter — a practical detail that makes a real difference when you’re picking this up with oily hands mid-run. The knurl gives you purchase without fumbling.
Compatibility — directly suits any bore micrometer, internal dial indicator, air gauge probe, or telescoping gauge calibrated in the 32mm range. No adapters required; simply present your measuring instrument to the bore, zero, and go.
Ideal for — zeroing bore micrometers prior to measuring bearing housings, hydraulic cylinder bores, and bushing fits; verifying internal dial indicator setup on a surface grinder chuck bore; setting air gauging equipment at the start of a production run; and confirming roundness checks on turned or honed bores at the 32mm nominal.
Condition
(Used — Good Condition / Light Workshop Patina)
The bore — the surface that actually matters on a setting ring — is in good working order. The ground internal surface shows no visible scoring, chatter, or wear steps that would affect your zero. The outer faces and knurled OD carry the expected patina of a used toolroom reference: light handling marks and superficial surface dulling consistent with bench use, but nothing structural. The engraved markings (ø32, –0.001, Ocean, D454) are fully legible. As with any used ring gauge, we recommend verifying the bore against a calibrated bore micrometer or air gauge before putting it into production service — this is standard practice regardless of age or source, and confirms the ring is still performing within its marked deviation. For jobbing shop, toolroom backup, or home workshop use, this ring will do the job reliably.
Included:
1 x Ocean D454 32mm Setting Ring (ø32, –0.001mm deviation)
1 x Original green presentation box
Not included: Certificate of calibration / NATA calibration documentation.
Brand Information
Ocean is a Japanese precision metrology brand with a long-standing presence in the toolroom gauge and reference standard market. Japanese metrology manufacturing — whether from the major names or specialist producers like Ocean — is held to tight process controls and sits comfortably alongside brands such as Niigata Seiki and RSK in terms of material quality and grinding standards. For a setting ring, where the geometry of the bore is the entire product, Japanese origin is a genuine indicator of dimensional reliability rather than a marketing badge.

The Ocean 76mm Setting Ring is a precision-ground internal reference standard used to set and verify bore measuring instruments to a known diameter. At ø76mm with a marked deviation of −0.001mm, this ring gives you a traceable reference point for zeroing bore gauges, internal micrometers, and air gauging systems — keeping your hole tolerances honest on the shop floor.
Precision-ground bore with −0.001mm deviation marking — The engraved correction value tells you exactly how far the actual bore differs from the nominal 76mm diameter. That single figure is what separates a setting ring from a rough spacer: you can apply the offset when zeroing your instrument and hold tighter tolerances with confidence.
Hardened steel construction with knurled OD — The outer diameter knurl gives a positive, non-slip grip when setting instruments by hand, while the hardened bore resists wear from repeated gauge contact. A soft bore would drift out of spec after modest use; hardened steel holds the reference geometry long-term.
Flat lapped face surfaces — The lapped top face is the datum for consistent axial positioning of the gauge. A true, flat face ensures your bore gauge sits square in the ring every time, eliminating cosine error that would otherwise creep into your readings.
Compatibility — Sized to set bore gauges, dial bore gauges, internal micrometers, and air gauging probes at the 76mm nominal. No additional accessories are required for standard setting use; a temperature-controlled surface or toolroom bench is recommended for best accuracy.
Ideal for — Zeroing dial bore gauges before checking cylinder bores, hydraulic cylinder IDs, and bearing housing bores; setting internal micrometers for bushing and sleeve inspection; verifying bore gauge calibration on a surface grinder or jig borer setup; and incoming inspection of turned or bored components to 76mm nominal.
Condition
Used (Good Condition / Previously Deployed, Stored Correctly)
The bore — the only surface that does the actual measuring work — is clean, free of visible scoring, and presents well under inspection. The lapped top face shows light service marks consistent with normal workshop handling but retains its flat reference character. The outer knurl is intact and functional. The seller has lubed the ring and plastic-wrapped it for storage, which is exactly the right practice for a hardened steel gauge: it prevents atmospheric rust and keeps the bore surface protected between uses. Some light surface patina is visible on the flat face, typical of a used toolroom piece that has seen honest work. The bore itself does not show the kind of ring-marking or contact wear that would indicate misuse or damage to the reference surface. As with any used setting ring, best practice is to verify the bore dimension against a known master or CMM before committing to tight-tolerance work — the engraved −0.001mm correction value should be confirmed rather than assumed, especially if the ring has been out of a calibrated environment for an extended period.

This vintage Peacock dial bore gauge set covers a 35–60mm measuring range and arrives as a complete kit — including its original wooden storage case and a Mitutoyo 2046F dial indicator that presents in near-new condition. Whether you’re checking cylinder bores, hydraulic valve bodies, or turned housing fits straight off the lathe, this is a toolroom-grade setup ready to go back on the bench without having to source a separate indicator or chase down extension rods.
35–60mm measuring range with interchangeable contact points — the full set of extension anvils is present, letting you step through the range without compromise. For a bore gauge to be genuinely useful across multiple jobs, a complete anvil set is non-negotiable; missing even one rod can leave gaps in your coverage.
Mitutoyo 2046F dial indicator included — the 2046F is a 0.01mm graduation, 10mm travel dial gauge from one of Japan’s premier metrology manufacturers. Pairing a known, trusted indicator with the bore gauge stem means your readings start from a solid reference rather than an unknown third-party gauge of uncertain accuracy.
Centralising / rocking measurement method — like all quality dial bore gauges, this tool is rocked across the bore to find true minimum deflection (the actual diameter). That technique filters out angular error and delivers consistent, repeatable readings that a telescoping gauge and micrometer combination simply can’t match for speed.
Complete original wooden case — the fitted wooden box keeps every anvil, spacer, and the indicator organised and protected. Losing small bore gauge components is a genuine frustration on a busy bench; having the original case means nothing rolls away.
Ideal for — checking engine cylinder bores and re-bore sizing, verifying turned housing and bearing housing fits, inspecting hydraulic cylinder and valve body bores, confirming bushing and sleeve press fits, and production incoming inspection of bored components in the 35–60mm class.
Condition
Used (Good Condition / Vintage Complete Set)
The Peacock bore gauge body and stem present with the honest patina you’d expect from a vintage Japanese instrument — there is age-related surface wear on the knurled grip and mild oxidation on the steel body consistent with decades of toolroom storage, but nothing that affects the measuring function or the integrity of the contact surfaces. The measuring anvils show no visible damage to their contact tips, and the centralising spring action functions correctly. The star of the show is the Mitutoyo 2046F dial indicator, which presents in like-new condition — the crystal is clear, the bezel rotates cleanly, the needle snaps back crisply with no drag, and the rack travel is smooth through its full 10mm range. All accessory anvils and spacers appear to be present per the original case layout. As with any used bore gauge, we recommend zeroing the instrument against a calibrated setting ring or a precision-ground plug gauge at the start of use to confirm zero and verify repeatability before committing to critical work. The wooden case shows age-related wear to its exterior finish but remains structurally sound and fully functional for storage and transport.

Paired with Peacock’s own No.36B dial indicator, this kit gives you a complete, ready-to-use internal measurement setup straight out of the case, without sourcing extra accessories. Whether you’re checking a freshly bored cylinder for taper and out-of-round, verifying a reamed housing bore against a H7 tolerance, or setting up a boring head for a precision fit, this gauge gives you the reach and resolution to do it properly.
50–100mm measuring range with graduated extension anvils — The kit ships with a full set of interchangeable measuring anvils (0.5, 1, 2, 3mm steps visible in the tray, scaling up to cover the full 50–100mm capacity). This matters because a bore gauge without its full anvil set forces you to compromise — gaps in coverage mean you’re either reaching for a different gauge or improvising. With the complete set, you can step through the range continuously without interruption.
Peacock No.36B dial indicator, 0.01mm graduation — The analogue dial indicator reads in 0.01mm increments, which is sufficient resolution for most production and toolroom bore checking. On a 0.01mm-per-division gauge, one graduation is roughly 0.4 thou — more than adequate for clearance fits, bearing housing checks, and cylinder ovality measurement where you’re working to tolerances in the order of 0.02–0.05mm.
Rigid one-piece gauge body — CG-3 series — The CG-3 body uses a centralising mechanism that self-centres the measuring head in the bore, ensuring the gauge always reads on the true diameter rather than a chord. This is the critical design feature that separates a dial bore gauge from a telescoping gauge — the reading is repeatable and operator-independent once you’ve found the rocking minimum, which is the correct measurement technique.
Complete kit in fitted case — All anvils, the gauge body, the dial indicator, and ancillary hardware are housed in the original moulded plastic case. A complete kit in its original case is worth noting — individual Peacock replacement anvils and spare parts aren’t always easy to source in Australia, so having every piece accounted for is a genuine practical advantage.
Ideal for — Cylinder bore measurement (taper, ovality, and wear checks on engine rebuilds), checking precision-bored housings and bearing fits, verifying reamed holes against H6/H7 tolerances, inspecting hydraulic cylinder bores, and production QC of machined bores in the 50–100mm range.
Condition
Used (Good Condition / Complete Kit, Minor Modification)
The gauge body and anvil set are in good working condition. The centralising head moves freely, the measuring anvils are present and undamaged, and the dial indicator (Peacock No.36B) functions as expected with a live, responsive needle. The critical precision surfaces — the measuring anvil contacts and the bore-contacting reference points — show normal workshop patina consistent with a used tool but no visible damage that would compromise measurement integrity. The anvil tray appears complete across the full range from 50mm to 100mm, with both the small-increment spacers (0.5, 1, 2, 3mm) and the larger stepped anvils visible and accounted for.
One modification requires clear disclosure: the rear mounting eyelet on the dial indicator has been cut off. This eyelet is used for lug-back mounting of the indicator to a stand or arm — its removal does not affect the indicator’s function when mounted in the bore gauge body, where it seats and clamps via the indicator stem in the conventional manner. However, if you intended to repurpose this indicator separately as a standalone dial indicator mounted to a magnetic base or indicator stand via the lug, that option is no longer available without a replacement indicator. For use as a dedicated bore gauge indicator — its primary purpose here — this modification is functionally irrelevant.
As with any used bore gauge, we recommend verifying zero against a calibrated ring gauge or a precision-bored master before putting this tool into critical production work. For general workshop use, engine rebuilding, and toolroom checking, it is ready to use as received.

The Peacock 107 is a Japanese-made dial indicator built to toolroom standards, offering 0.01 mm graduation across a 10 mm measuring range in a compact, balanced body that sits comfortably in a magnetic base or indicator holder. Manufactured by Ozaki Mfg. Co. in Japan, this gauge carries the same pedigree trusted by precision shops across Asia, Australia, and Europe for decades — and this example is New Old Stock, never put to work.
0.01 mm graduation over a 10 mm range — A full centimetre of travel with one-hundredth resolution means you can run the spindle through its full stroke without resetting, making it practical for both fine runout checks and larger setup verification tasks where a shorter-range gauge would require multiple repositions.
Revolution counter sub-dial — The small secondary dial tracks full revolutions of the main pointer, so you always know where you are in the 10 mm travel. Critical when checking deep bores or tall workpieces where it’s easy to lose track of how many times the needle has swept past zero.
Balanced bezel and rotating outer ring — The knurled bezel rotates to allow easy zero-setting without moving the gauge body, keeping your setup undisturbed once you’ve clocked in a vice or trammed a head. The 58 mm dial face is large enough to read comfortably across a machine table.
8 mm stem / shank diameter — The standard 8 mm stem fits the vast majority of magnetic bases, dial indicator holders, and arm clamps found in Australian workshops. No adaptor required for most setups; universal compatibility straight out of the box.
Ideal for tramming mill heads and vices, four-jaw chuck centring on the lathe, checking lathe spindle runout, surface grinder wheel and chuck runout verification, scribing reference lines off a ground surface, and parallels / fixture height comparison on a surface plate.
Condition
New Old Stock (Unused / Original Packaging, Undisplayed)
This gauge presents as fully unused. The dial face is clean with no scratches, smears, or UV fade. The chrome bezel and body show no handling marks, and the contact point tip and stem are free of the wear witness marks you’d expect on any used indicator — no flat spot on the point, no scuff ring on the stem from clamp contact. The movement is smooth through its full 10 mm stroke with no sticky spots or backlash hesitation, and the pointer returns crisply to zero on release. As New Old Stock, the gauge has been stored rather than used, so it comes with its original calibration certificate — however, given the nature of NOS inventory, a quick verification against a known master or gauge block stack before committing it to critical work is always sound practice. Mechanically and cosmetically, this example is as close to out-of-the-factory condition as a pre-owned purchase gets.

Peacock PIC-TEST PC-1L Dial Test Indicator — Long Stylus
The Peacock PC-1L is a jewelled dial test indicator built to Japanese toolroom standards — the kind of instrument that earns its place on a surface plate or mag base and stays there for decades. With a 0.01 mm graduation and a balanced bidirectional dial, this is a workhorse indicator suited to the bench, the mill, and the lathe. The long stylus configuration extends reach into bores, deep pockets, and awkward setups where a standard-arm indicator simply can’t get a clean contact point.
0.01 mm graduation (jewelled movement) — The jewelled pivot bearings reduce friction and backlash in the gear train, which translates directly to repeatable, reliable readings across the full sweep. At 0.01 mm resolution you’re working in the same territory as a good tenths indicator for most practical alignment tasks — enough precision for tramming, runout checks, and surface verification without the fragility of a 0.001 mm instrument.
Balanced bidirectional dial face — The dial reads from 0 at centre to 50 in both directions, letting you use either direction of stylus deflection without re-zeroing or mental arithmetic. Useful when picking up off a datum and reversing direction mid-setup.
Long stylus arm — The extended stylus increases effective reach, which matters when you’re probing inside a bore, reaching past a chuck jaw, or contacting a surface that a standard short-arm indicator can’t access cleanly. Contact point geometry stays consistent, which matters for accurate runout and concentricity readings.
Compatibility — The PC-1L uses a standard dovetail mount and is compatible with Peacock PIC-TEST mounting clamps and universal indicator holders. The cylindrical boss on the indicator body accepts common mag base and arm-type holders. Replacement contact points are available through Peacock and compatible aftermarket suppliers.
Ideal for — Tramming a mill head, setting a four-jaw chuck for concentricity, checking spindle runout on a lathe, aligning a vice parallel to the table, verifying flatness on a surface plate, and probing deep bores or recesses where a short-arm indicator loses contact.
Condition
Used (Good Condition / Pre-owned, Functional)
Mechanically, this indicator is in good working order. The movement responds promptly to stylus deflection, the needle returns to zero cleanly with no evidence of sticking or backlash in the gear train, and the dial glass is intact and clear. The chrome body shows the kind of light handling marks and bench patina you’d expect from a used instrument — nothing that affects the precision surfaces or the movement. The dovetail mount and stylus arm show no visible damage or deformation. As with any used precision instrument, we recommend verifying zero and repeatability against a known reference — a gauge block stack or ring gauge — before putting it into production use. That’s standard practice for any secondhand indicator, regardless of brand or condition.

The RSK 42mm Plain Setting Ring is a precision ground bore reference standard used to set and verify internal measuring instruments — bore gauges, air gauges, and three-point internal micrometers — to a known diameter before you put them to work on the job. At 42mm nominal diameter, this ring covers a size that comes up constantly in shaft-and-bore fitment work, bearing housing checks, and hydraulic cylinder inspection. It’s a toolroom staple, not a nice-to-have.
Precision ground internal bore — the working surface that matters. The bore of a setting ring is lapped and ground to extremely tight tolerances, giving your bore gauge a stable, repeatable zero reference. Without a traceable setting ring, you’re zeroing off your own part — and that’s circular logic on the shop floor.
Hardened steel construction. The ring is manufactured from hardened tool steel, which resists wear on the internal datum surface across years of regular use. A soft ring would drift out of spec every time an instrument was set against it, defeating the purpose entirely.
Knurled outer diameter for secure handling. The aggressive knurl on the OD gives a positive grip when you’re setting a bore gauge one-handed at the bench — no fumbling, no dropping a precision standard onto the concrete floor.
Compatibility. Suits any bore gauge, air gauge plug, or three-point internal micrometer with a range covering 42mm nominal diameter. No additional accessories are required to use the ring — it is a self-contained reference standard. A calibration certificate is included, allowing traceability back to a known standard.
Ideal for: Zeroing bore gauges for bearing housing inspections, setting three-point internal mics for hydraulic cylinder bore checks, verifying bore gauge repeatability before a precision fitting run, and incoming inspection of 42mm nominal bores on turned components.
Condition
Used (Good Condition / Previously Calibrated, Includes Certificate)
The bore — the only surface that does any real work — is in good condition, retaining the ground finish required for accurate instrument setting. The external faces show the honest patina of a used precision tool: light surface oxidation and minor handling marks are visible on the flat faces and OD, consistent with bench use and storage. The unit has been lubricated and plastic-wrapped for storage, which is correct practice for preserving a hardened steel reference standard. There is no visible damage to the bore surface, no scoring, and no corrosion pitting on the internal datum that would compromise its function as a setting reference. The engraved markings — ø42 nominal diameter and the RSK brand stamp with serial number — are legible. As with any used setting ring, independent verification against a calibrated CMM or comparator is recommended before relying on it for tight-tolerance work, particularly if your process demands traceability to NATA-accredited standards. The included calibration certificate provides a documented reference point for that verification.

The Sandvik Coromant S20S-CTFPR-11 is a 20mm round-shank, right-hand boring bar designed for internal turning and profiling operations on CNC lathes and turning centres. Built to accept TPFR-style triangular negative inserts (TPMT/TPGT 110308 / 11T308 series), this bar is engineered for precision internal work where rigidity, repeatability, and consistent insert indexing matter most. New Old Stock, still in original packaging — a genuine opportunity to put a premium Sandvik Coromant boring bar on your turret at used-tool pricing.
20mm round shank with 200mm (approx.) overhang capacity — The S20S designation confirms a 20mm shank diameter. A steel-bodied boring bar at this shank size delivers the rigidity needed to hold diameter tolerance on internal bores without chatter, particularly in shorter-to-medium overhangs typical of CNC lathe turret work.
CTFPR-11 insert pocket geometry — The CTFPR designation specifies a right-hand cutting direction with a 91° lead angle, using screw-clamp (top-clamp) retention for triangular (T-style) negative inserts. This geometry produces excellent chip clearance on through-bores and blind-bore profiling, and the negative rake keeps cutting forces predictable on steels and cast irons.
Compatible with TPMT / TPGT 110308 (11T308) insert range — The “-11” suffix confirms the IC (inscribed circle) size: 11mm triangular inserts. Sandvik’s own CoroTurn 107 TPGT 110308 inserts are the go-to choice, available in grades covering steels (GC1125, GC4325), stainless (GC2025), cast iron (GC3210), and non-ferrous (H13A). Third-party TPMT 110308 inserts are widely compatible and cost-effective for roughing work.
Steel shank construction — Standard steel-body boring bars suit the majority of internal turning applications where bore diameters and overhangs are within conservative L/D ratios (generally up to 4×D). For extreme overhangs, Sandvik’s carbide-shank or Silent Tools variants would be the step up — but for everyday CNC lathe boring work this bar is the right tool.
Ideal for — Internal diameter turning and finishing on CNC lathes; profiling stepped and chamfered bores; boring to close-tolerance fits (H7/H6) in steel, cast iron, aluminium, and brass; production and one-off toolroom turning where consistent insert indexing and repeatable tool offsets are critical.
Condition

This boring bar presents well, the shank shows no chuck marks, turret-clamp witness marks, or wear to the precision-ground shank diameter. The insert pocket is clean with no carbide rub, seating-face wear, or damaged screw threads. The clamping screw and any original accessories included by Sandvik are present. Surfaces may carry a light storage patina or minor oxidation on non-ground areas of the shank from shelf time — this is cosmetic only and has zero impact on the bar’s dimensional accuracy or function in the turret. The ground shank diameter is the reference surface that matters, and it is clean.

A precision setting ring is one of those toolroom staples that earns its keep every single day — and this SHS 35.9985 mm setting ring is a textbook example of why. Ground and lapped to a nominal 36 mm bore, this hardened steel ring gauge is used to set and verify bore measuring instruments to a known reference diameter, taking the guesswork out of internal measurement. Whether you’re qualifying a new bore mic, zeroing a plug gauge, or verifying a bore comparator before a production run, a traceable setting ring is the ground reference you need to trust your readings.
Ground and lapped bore to 35.9985 mm actual size — the stamped actual size matters more than the nominal. This ring has been measured and engraved at 35.9985 mm, meaning you’re setting your instrument to a known, specific diameter rather than assuming nominal — critical when you’re working to tight tolerances and every tenth counts.
Hardened steel construction — the bore surface is hardened to resist wear from repeated gauge insertion. A soft ring gauge deteriorates quickly in production use; a hardened ring holds its geometry over thousands of insertions, maintaining its value as a reliable reference standard.
Compact, stable ring form — the substantial wall thickness and disc geometry give this ring excellent dimensional stability. It won’t distort under handling or temperature fluctuation the way a thin-walled component might, which matters when you’re chasing single-figure micron accuracy.
Compatibility — suits bore micrometers, bore comparators, air gauges, and plug gauges in the 36 mm range. No additional accessories are required to use this as a setting standard; simply clean the bore, insert your instrument, and zero.
Ideal for — setting bore micrometers prior to measuring engine bores, gearbox housings, and hydraulic cylinder bores; qualifying bore comparators before a production run; verifying plug gauge wear; and incoming inspection of machined bores on the bench or CMM room.
Condition
(Used — Good Condition / Toolroom Surplus)
The bore surface — the functional datum of this gauge — presents well, with no visible scoring, pitting, or fretting evident on the lapped internal diameter. The outer diameter shows the expected patina and minor handling marks consistent with toolroom use and storage, but these surfaces are cosmetic only and have no bearing on the gauge’s working accuracy. The engraved actual size marking of 35.9985 mm is clearly legible. The date code stamped “95-11” indicates manufacture or calibration in November 1995, which is consistent with this type of long-life hardened gauge standard. As with any used setting ring, we recommend verifying the bore diameter against a calibrated reference or CMM before committing it to critical inspection work — this is standard practice with any second-hand metrology standard regardless of apparent condition. For general bore mic setting and comparator zeroing in a job shop or home machining environment, this ring is fit for purpose as presented.

1 x SHS Setting Ring — 35.9985 mm actual bore diameter (nominal 36 mm)
1 x Original red presentation / storage box

The Tesa Universal Dial Protractor is a precision angular measurement instrument built for the toolroom bench — combining a circular dial readout with a versatile blade arrangement that makes reading compound angles fast, repeatable, and far less prone to parallax error than a traditional vernier bevel protractor. If you’re setting up bevel gears, checking taper angles on a lathe compound, or verifying chamfer angles on ground components, this is the instrument that earns its keep.
Dial-read angular measurement to 5-minute resolution — The circular dial face replaces the vernier scale of a conventional bevel protractor, giving you a clear, direct reading without the eye strain of counting fine vernier divisions under workshop lighting. At 5-minute (5′) graduation, it’s precise enough for the vast majority of toolroom angular work where degree-and-minute accuracy is required.
Full 360° measurement range — The instrument measures any angle from 0° to 360°, meaning you’re not forced to flip or reposition the blades to tackle obtuse or reflex angles. This is a genuine time-saver when checking internal and external bevels on the same component setup.
Hardened and ground blade construction — The straight blades provide a reliable ground reference edge for accurate contact against machined surfaces. Ground blades hold their flatness in service and resist the wear that plagues cheaper stamped alternatives, keeping your measurement edge honest over years of use.
Adjustable blade configuration with locking screws — The main and auxiliary blades are independently adjustable and lock down firmly, allowing the instrument to be set to a known angle and used as a direct reference for scribing, setting, or gauging — useful when transferring angles to a sine bar setup or checking a batch of components.
Ideal for — setting compound slide angles on a manual lathe, checking taper plug and ring gauge angles, verifying dovetail slide angles on milling machines, inspecting bevel gear tooth angles, setting up angled vices and tilting tables on surface grinders, and scribing accurate angular layout lines in toolmaking.
Condition
Used (Good Condition / Pre-owned, Functional)
This Tesa Universal Dial Protractor presents well for a used instrument. The dial mechanism operates smoothly, the pointer moves freely without sticking, and the blade locking screws engage and hold as intended — which is the core functional requirement for this type of instrument. The ground blade edges show the kind of light patina and minor handling marks you’d expect from a toolroom instrument that’s actually been used; there are no visible chips, burrs, or deformation to the reference edges that would compromise contact accuracy. The dial crystal (or cover) is intact with no cracking that would interfere with reading. As with any pre-owned dial protractor, it is good practice to verify the zero against a known reference square before putting it into critical measurement service — a simple check against a precision ground parallel or a reliable engineer’s square will confirm the instrument is reading true. The original wooden case, instruction papers, and original accessories are all present, which is increasingly uncommon for instruments of this age and is a strong indicator that this set has been looked after.
Included:
1 x Tesa Universal Dial Protractor (complete instrument with dial head and blades)
1 x Original wooden storage case
1 x Original instruction / specification papers (French language, consistent with Tesa’s Swiss/European origin)
Original accessories as supplied (as visible in case)
Not included: No additional setting masters or calibration certificates are included. Calibration certificate not supplied — buyer should verify zero and angular accuracy against a known reference prior to use in certified inspection work.
