Mitutoyo Dial Gauge 2046S

Mitutoyo 2046S Dial Gauge — 0–10mm, 0.01mm Graduation

The Mitutoyo 2046S is a workshop staple for a reason. This 0–10mm travel dial gauge with 0.01mm graduation delivers the kind of repeatable, reliable readout that machinists and toolmakers have trusted for decades — on the surface grinder, on the mill, or bolted to a mag base checking runout on the lathe. Made in Japan, built to Mitutoyo’s exacting tolerances, and designed for the daily grind of a production or toolroom environment, the 2046S punches well above its weight class. This one is ready to go straight onto a mag base and get to work.

0–10mm measuring range with 0.01mm (one-hundredth) graduation — Full millimetre travel makes this gauge genuinely versatile. You’re not limited to fine surface checking; 10mm of range means it’s equally at home tramming a mill head, checking parallelism on a surface grinder table, or setting up a four-jaw chuck where you need a bit of travel before you start dialling in.
Balanced continuous dial face with revolution counter sub-dial — The large, clearly graduated main dial reads 0–100 divisions across the full face, while the small sub-dial tracks full millimetre revolutions. In practice, this means you’re not losing count of how many times the needle has lapped — critical when you’re doing a runout check and need to know total indicator reading (TIR) at a glance.
Shock-proof (dust-proof) construction — Mitutoyo No. 2046S — The ‘S’ designation on this series denotes shock-proof internals, meaning the gear train and jewelled movement are protected against the kind of accidental knocks that happen in a working shop. A non-shock-proof gauge dropped from mag-base height can end its working life on the spot. This one is built to survive.
8mm stem / lug mount — universal compatibility — The 8mm cylindrical stem is the industry standard for dial indicator holders and magnetic base clamps. It’ll seat in virtually any mag base, Noga-style arm, surface gauge, or dedicated indicator holder without adapters. The seller notes the round mounting pin (lug) is screwed in and compatible with eyelet-style magnetic arms — worth confirming your arm’s clamp style before you order if you’re running a non-standard setup.
Ideal for — tramming mill heads and vices, four-jaw chuck runout setup, lathe between-centres alignment, surface grinder table flatness checks, press-tool alignment, and any application where you need reliable 0.01mm resolution over a generous travel range.

Condition

Used (Fair Condition / Functional Working Tool — Cosmetic Wear)

Mechanically, this gauge is doing what it needs to do. The needle moves smoothly across the full 0–10mm travel, returns to zero consistently, and tracks with the repeatable response you’d expect from a Mitutoyo movement — no sticky zones, no backlash drag, no dead spots. The sub-dial revolution counter functions correctly. The spindle and contact point move freely without side-play.

Cosmetically, the dial face shows the honest wear of a tool that’s been used — visible marks and light scratches on the crystal and face. This is surface-level; it doesn’t affect readability at normal working distance, and it has zero bearing on measurement accuracy or repeatability. The case and bezel carry the expected patina of a shop-used instrument — not pretty, but structurally sound. There are no cracked or missing components, and the bezel rotates correctly for zeroing.

For a tool at this price point, we’d recommend a quick verification check before putting it into critical inspection work — zero it against a known reference and run the plunger through its full travel a few times to confirm consistent return. For tramming, runout checks, setup work, and general toolroom duties, this gauge will perform exactly as intended. If you’re pulling it into a formal inspection role, a calibration check against a certified master is always good practice with any used indicator, regardless of brand.

Noga NF10403 Mag Fine Adjust Base

Product Overview

This is a premium Noga Articulating Mini Magnetic Base (matching the NF-series profile), specifically featuring the highly desirable Fine Adjustment at the Base. It is the ultimate setup companion for precise dial test indicator (DTI) alignment in tight machining envelopes.

Base-Mounted Fine Adjust: Unlike models with the adjustment knob up at the indicator head, having the fine-tuning mechanism down at the magnetic base is a game-changer. It means your hand is resting solidly near the machine table while you turn the screw, preventing you from accidentally bumping or vibrating the delicate indicator setup while trying to sweep it to zero.
Single-Point Articulation: Noga is famous for its central locking mechanism. By turning one single knob, the bottom, middle, and top joints all lock up simultaneously with absolute, rock-solid rigidity.
Universal Swivel Clamp: The top clamp is designed to securely grip both 6mm stems and standard dovetails. This means it will perfectly hold almost any lever-style dial test indicator in your shop.
Compact Footprint: As a smaller-profile base, it is perfect for clamping onto lathe chucks, small milling machine tables, or sliding headstock (Swiss) machines where a full-sized mag base simply gets in the way.

Condition

Used (Good Condition / Fully Functional).

This Noga base is in used condition and shows typical signs of shop wear.

Mechanical Integrity: The most important part of any used Noga is the locking cam. This unit has been checked, and the central locking knob tightens down securely, locking the arms rigidly without creeping or sagging. The magnet switches on and off cleanly with strong holding force. (Note: While the exact model number sticker may be worn or point to a similar NF series, the physical configuration is guaranteed as a base-adjust model).

Brand Information

Noga Engineering (Israel) is universally recognized by machinists as the absolute gold standard for magnetic bases and indicator holders. While their single-knob articulating design has been heavily cloned by budget brands, the holding power, buttery-smooth joints, and durability of a genuine Noga have never been matched.

Mitutoyo 25-50mm Digit Micrometer 193-112

Product Overview

The Mitutoyo 193-112 is a 25–50mm outside micrometer with an integrated mechanical digit counter — a tool built for machinists who want fast, unambiguous readings without squinting at vernier lines. The rolling digit display eliminates interpolation error on the sleeve and suits the kind of high-repetition measuring work where thimble misreading costs time and scrapped parts. Japanese-built to Mitutoyo’s exacting toolroom standards, this is a bench instrument that earns its keep on a production floor or in a serious home shop.

Mechanical digit counter (0.001mm resolution) — The rolling counter reads directly in millimetres and hundredths, bypassing the need to read sleeve graduations and mentally add the thimble. In high-cycle measuring environments — incoming inspection, turned diameter checks, shaft fits — this pays back its premium in eliminated reading errors and faster throughput.
25–50mm measuring range — Covers the most common mid-range shaft, boss, and bearing-seat diameters encountered on the lathe or surface grinder. A 0–25mm mic handles small work; this one picks up where it leaves off and takes you through M30–M48 bolt bosses, bearing journals, and chuck jaw register fits.
0.001mm (1 micron) graduation — At one thou of a millimetre, this instrument resolves tolerances well inside most h6/H7 fits and is more than adequate for ISO general tolerance work, toolroom fits, and pre-grind stock allowance checks.
Carbide-tipped anvil and spindle faces — Mitutoyo fits the 193-series with hardened and lapped carbide measuring faces. Carbide resists the wear that kills flat-face accuracy on a plain steel mic, meaning the instrument holds its calibration longer under regular production use.
Ideal for — Checking turned shaft diameters to drawing tolerance, measuring bearing journal fits before pressing, verifying ground-stock OD before hardening, pre-measurement checks on CNC turned components, and incoming inspection of fastener and pin ODs in the 25–50mm range.

Condition

Used (Like New / Full Kit, Minimal Use)

This micrometer presents in excellent used condition with clear evidence of only light prior use. The carbide measuring faces are clean, flat, and free from visible pitting, scoring, or contact damage — the surfaces that determine accuracy are in sound shape. The frame finish retains the majority of its original lacquer with only minor handling marks consistent with careful bench use; no corrosion, no impact damage, and no distortion to the frame. The thimble and sleeve operate smoothly with good feel throughout the range, the ratchet stop functions correctly, and the digit counter rolls cleanly without sticking. The lock nut engages positively. As with any used precision instrument, verification against a 25mm setting standard (ring gauge or certified gauge block stack) before putting it into production is standard workshop practice — not a flag on this particular tool, just sound metrology habit.

Included:

1 x Mitutoyo 193-112 Outside Micrometer, 25–50mm, 0.001mm, Digit Counter
1 x Original Mitutoyo fitted case
1 x 25mm setting standard / reference gauge
1 x Original paperwork / warranty documentation (Japanese language)

Mitutoyo 0-25mm Digital Micrometer 293-240-30

Product Overview

The Mitutoyo 293-240-30 is a 0–25mm digital outside micrometer from the QuantuMike series — one of Mitutoyo’s most refined bench micrometers for precision work where speed and accuracy need to coexist. With a fast-feed thimble mechanism, IP65 coolant-proof rating, and a 0.001mm resolution digital readout, this is a toolroom-grade instrument that earns its place next to your surface plate or beside the spindle of a CNC lathe. Whether you’re checking turned diameters to the thou, qualifying stock before a grinding pass, or doing first-off inspection on a batch of precision shafts, the 293-240-30 delivers repeatable, traceable readings without the ambiguity of a vernier line.

0.001mm resolution digital readout with IP65 protection — The LCD display eliminates parallax error and interpolation guesswork that comes with analogue thimbles. IP65 coolant-proof sealing means you can use this instrument at the machine in a flood-coolant environment without babying it — a meaningful real-world advantage over standard digital micrometers that fail quickly in wet shop conditions.
Fast-feed thimble mechanism (QuantuMike) — The QuantuMike’s rapid advance mechanism lets you spin the thimble down to the work much faster than a conventional micrometer without sacrificing feel at the measuring face. On production work or repeat checking of multiple parts, this cuts cycle time at the gauge station and reduces operator fatigue over a long shift.
Hardened and ground carbide-tipped anvil and spindle faces — Both measuring faces are carbide-tipped and lapped flat, giving the instrument long service life under daily use. The ground reference surfaces are what underpin repeatable, accurate measurements — this is not a cost-reduced instrument with painted or plated faces.
SR44SW battery included; Origin/Zero/Hold functions — The ORIGIN function allows the micrometer to be zeroed at any point in the range, useful when checking wall thickness or step dimensions. The HOLD function freezes the display — handy when measuring in restricted access or at awkward angles where you can’t see the display at the point of measurement.
Ideal for — first-off and in-process inspection of turned and ground components, qualifying bar stock and ground shafting before setup, checking micrometer-critical fits (bearing journals, gear bores, bushings), QC inspection on CNC lathe and mill work, and toolroom gauge-bench duties where a calibration certificate is required for traceability.

Condition

New (Factory Sealed)

This micrometer is brand new and factory sealed in the original Mitutoyo packaging. The measuring faces, thimble, sleeve, and frame are in pristine, unissued condition — no contact marks on the anvil or spindle, no wear on the thimble knurl, and no handling patina on the frame. The instrument has not been used, set up, or zeroed prior to this sale. A Mitutoyo Certificate of Inspection is included confirming the unit has passed factory calibration and is traceable to national measurement standards (NIST/JCSS). As with any precision instrument — new or used — it is good shop practice to verify zero against a known reference (a calibrated 25mm gauge block or setting standard) before putting it to work, particularly if the unit has been in transit. The certificate documents factory-measured errors at multiple points across the range, so you have a documented baseline from the outset.

Included:

1 x Mitutoyo QuantuMike Digital Outside Micrometer, 0–25mm, 0.001mm resolution (Model 293-240-30)
1 x Original Mitutoyo fitted carry case
1 x Certificate of Inspection / factory calibration documentation
1 x SR44SW battery (installed)
1 x Spanner wrench / standard accessories as supplied by Mitutoyo
1 x Instruction manual / documentation pack

Mitutoyo 2 Micron Indicator 513-475-10 Ruby Tipped

Product Overview

Sometimes, a standard 0.01mm indicator isn’t precise enough, but an ultra-sensitive 1-micron indicator is too twitchy for your specific setup. The Mitutoyo 513-475-10 Horizontal Dial Test Indicator hits the absolute sweet spot. Offering a highly precise 2 Micron (0.002mm) resolution and a durable ruby tip, it provides incredible accuracy while remaining highly readable and stable during demanding metrology tasks.

The 2-Micron Sweet Spot: Featuring a strict graduation of 0.002mm and a total measuring range of 0.2mm (0-100-0 dial reading), this instrument is the perfect middle ground for indicating aerospace parts, tramming fixtures, and checking high-precision runout without the needle jumping erratically from ambient machine vibration.
Ruby Contact Point: The stylus is tipped with a premium ruby ball. Ruby offers exceptional wear resistance against hardened tool steels and abrasive materials. Furthermore, it is completely non-magnetic, making this the ultimate indicator for use on magnetic surface grinder chucks or around high-powered EDM setups where a standard steel tip would stick and drag.
Jeweled Movement: Equipped with Mitutoyo’s legendary jeweled bearing mechanisms inside the housing, it provides buttery-smooth, highly responsive motion with zero clutch backlash and extremely low measuring force.
Shop-Floor Durability: The O-ring sealed bezel and hard-coated, glare-free crystal actively prevent the ingress of shop dust and aggressive cutting fluids, ensuring the dial face remains crystal clear over a lifetime of use.

Condition

Mitutoyo 2µm Test Indicator 513-405-10E

Product Overview

The Mitutoyo 513-405-10E is a lever-type dial test indicator built to the exacting standards that have made Mitutoyo the benchmark name in toolroom metrology. With a 2µm graduation and a compact dovetail-mount body, this indicator is engineered for the kind of close-tolerance work where a 5µm indicator simply won’t cut it — think surface grinder setup, precision boring, or holding a four-jaw to within a tenth. Fresh from the factory with its calibration certificate intact, this is a ready-to-use instrument that goes straight onto the bench with full traceability.

2µm (0.002mm) graduation over a 0.2mm measuring range — The fine graduation isn’t just a spec-sheet number. When you’re sweeping a ground bore or tramming a precision vice, each needle division represents two microns of deviation. That resolution lets you split the difference between graduations with confidence, delivering the kind of discrimination you need when tolerances are tight and scrap is expensive.
JIS B7533 / ISO 9493 / ASME B89.1.10M compliant accuracy — The included calibration certificate documents measured errors against the permissible limits under all three major international standards. For work going into aerospace, defence, or any regulated environment, that traceability back through NMIJ/AIST via JCSS to NIST and PTB is not optional — it’s the difference between a piece of paper you can hand to a customer and an educated guess.
Dovetail body with adjustable contact point — The universal dovetail mounting is compatible with the full range of Mitutoyo indicator holders, magnetic bases, and surface gauge posts. The articulating contact arm allows the stylus angle to be set without disturbing the mount, which matters when you’re reaching into a pocket or sweeping a bore from a fixed arm position.
Yellow dial face with ruby contact point — The high-contrast yellow dial with black graduations is easy to read under typical workshop lighting without squinting. The ruby contact tip resists wear on hardened surfaces far better than carbide or steel alternatives, keeping your contact geometry consistent over thousands of measurement cycles.
Ideal for precision surface grinder work-holding setup, four-jaw chuck centring, boring bar runout checks, tramming mill heads and vices, CMM fixturing verification, and incoming inspection of ground or turned components.

Condition

New (Factory Sealed)

This indicator is new and factory sealed — it has not been used, mounted, or touched by anyone between Mitutoyo’s production line and this listing. The instrument arrives with its original Mitutoyo plastic case, full accessory complement, documentation, and — critically — the original calibration certificate issued at 20°C standard temperature with a certificate number (4505466959) and QC manager sign-off. The certificate charts measured errors for upward and downward travel across the full measuring range, confirming the unit passed all JIS, ISO/DIN, and ASME repeatability requirements. There is nothing to disclose in terms of wear, surface marks, or mechanical issues — the tool is exactly as Mitutoyo shipped it. For the highest-confidence work, we still recommend zeroing against a known reference after any storage period or temperature change, as is standard practice with any precision instrument regardless of its newness.

Mitutoyo Micrometer Stand 156-101-10

Condition

New.

This micrometer stand is a brand-new, unused item. It is supplied in its original manufacturer packaging, with the stand itself still wrapped for protection. It is 100% complete and ready for immediate use on the inspection bench.

Product Overview

The Mitutoyo 156-101-10 is an essential workshop accessory designed to free up the operator’s hands for precise measurement. By clamping the micrometer frame in this dedicated stand, you can hold the workpiece with one hand and operate the thimble with the other, ensuring perfect alignment and consistent measuring force.

This specific model is the Adjustable Angle Type, allowing the micrometer to be tilted to the optimal viewing position for the operator. It features a heavy, cast-iron base for stability, preventing the setup from tipping over during use. The clamping jaws are lined with rubber/synthetic pads to securely grip the micrometer frame without scratching the hammertone finish or crushing the thermal insulation plates. It is designed to accommodate standard outside micrometers with ranges up to 100mm (4″).+1

Brand Information

Mitutoyo Corporation (est. 1934) is the global authority in dimensional metrology. While often overlooked, a high-quality stand is critical for achieving the rated accuracy of their micrometers. By isolating the tool from the operator’s body heat (which causes thermal expansion in the frame), the 156-Series stands ensure that measurements remain stable even during long inspection sessions.+1

Nakane Slender Chuck 3-4-6mm

Product Overview

The Nakane Slender Chuck is a purpose-built end mill holding system designed for CNC machining centres and manual mills where a standard chuck body would foul the workpiece or fixture. The slim-profile holder keeps the collet nose close to the spindle centreline and well clear of surrounding clamps, allowing deep-pocket and tight-clearance work that a conventional ER collet chuck simply can’t reach without extending the tool to a dangerous overhang. This set covers the three most common small end mill shank diameters in a single kit — a practical shelf item for any toolroom running die work, mould cavities, or detailed profiling.

Slender body geometry — the reduced-diameter holder body dramatically improves clearance in confined pockets and around workholding hardware, letting you run shorter tool stickout and recover rigidity that would otherwise be lost to extension.
Three-collet coverage (ø3.0, ø4.0, ø6.0 mm) — spans the small-diameter end mill range most commonly used in die-sinking and detailed profiling work; swapping collets takes seconds and the sizing covers the majority of jobs without reaching for a second holder.
Precision ground collet bore — a well-manufactured slender chuck collet grips on the full shank diameter with even clamping pressure, keeping runout tight and protecting the end mill cutting edges from the fretting that a loose or worn collet causes under interrupted cuts.
Compact elongated holder shank — the long, slim shank visible in the box is ground to a standard arbour diameter, allowing the holder to seat concentrically in a standard spindle taper or toolholder without introducing additional runout at the collet nose.
Ideal for — deep-pocket CNC milling, mould and die cavity work, profiling around vise jaws and clamps, running small carbide end mills in a manual knee mill where clearance is tight, and anywhere a standard shell mill arbour or ER block body would contact the fixture.

Condition

Used (Good Condition / Original Box, 3mm Collet Pitting Noted)

The holder body and elongated shank present well — ground surfaces show normal bench patina consistent with careful use, with no visible damage to the shank diameter or collet seat that would introduce gross runout. The ø4.0 mm and ø6.0 mm collets are in serviceable condition; their bores and external tapers appear clean and free of the kind of corrosion or scoring that would compromise grip or concentricity. The ø3.0 mm collet is the one component that warrants a straight conversation: it has sustained surface rust that has been cleaned back, but the cleaning has left visible pitting on the external taper face. Pitting on the collet OD taper is a functional concern — if the pitted surface doesn’t seat evenly against the chuck bore, it can introduce runout at the tool tip that a sound collet would not. For non-critical profiling, slotting, or roughing in 3 mm, the collet may perform adequately, but for finish work or anywhere you’re holding tight tolerances on a 3 mm shank tool, we recommend checking runout against a known ground test bar or replacing the 3 mm collet before committing it to precision work. The 4 mm and 6 mm collets carry no such reservation and should go straight to work. Original box and foam tray are included and the packaging has done its job — the holder has been protected.

Included:

1 x Nakane Slender Chuck Holder (elongated slim-body shank)
1 x ø3.0 mm Collet (pitting on external taper — see condition notes)
1 x ø4.0 mm Collet
1 x ø6.0 mm Collet
1 x Original Nakane box and foam tray

Not included: Spanner / tightening wrench (if required for the collet nut — source separately to suit your holder configuration), replacement 3 mm collet.

Brand Information

Nakane is a Japanese precision tooling manufacturer with a solid reputation in the toolroom and die-making sectors, producing collet chucks, holders, and related workholding accessories to the exacting tolerances expected of Japanese industrial tooling. Japanese tooling of this type sits comfortably alongside brands such as NT Tool, Nikken, and Big Kaiser in terms of manufacturing quality — ground to consistent tolerances, with material selection and heat treatment appropriate to a precision spindle component. While Nakane doesn’t carry the same global marketing presence as the largest Japanese tooling houses, the build quality evident in this style of product reflects the standards Japan’s machine tool industry is known for, and sourcing Nakane tooling second-hand remains a cost-effective path to quality Japanese precision over generic import alternatives.

New Strong Tools Toe Clamps TC-1B

Product Overview

Strong Tools TC-1B Toe Clamps are a purpose-built workholding solution for milling machine tables, designed to grip workpieces low and laterally — ideal when conventional strap clamps would foul the cutter path or where vertical clamping isn’t practical. The serrated toe face bites into the workpiece side, and the stepped base locates cleanly in a standard T-slot, giving you a compact, repeatable hold without stacking up a tower of strap-and-bolt hardware. These are sold as a matched pair of two clamps.

Serrated jaw face for positive lateral grip — The knurled/serrated toe face digs into the workpiece side wall, resisting both lateral pull and rotational shift under cutting loads. On interrupted cuts or heavy side-milling passes, this is the difference between a secure setup and a shifted job.
Stepped T-slot base design — The stepped foot profiles on each clamp are machined to engage standard T-slots, locking the clamp body against rotation and rocking. This means the clamping force goes where it’s supposed to — into the workpiece — not wasted fighting clamp movement.
Compact 105mm × 35mm footprint — At 105mm long and 35mm wide, these clamps sit tight to the workpiece with minimal table real estate consumed. On a crowded table with multiple ops or a second vice in use, that footprint matters when you’re trying to keep the cutter clear.
27mm jaw face height — The 27mm vertical gripping face gives adequate bite on low-profile workpieces such as plate sections, flanges, and sheet goods that conventional strap clamps struggle to reach down to cleanly.
Ideal for — Side-clamping plate and billet work on a knee mill or machining centre, holding irregularly shaped castings that won’t strap-clamp flat, fixturing thin-section parts for face milling, and any milling setup where the top surface of the workpiece must remain fully accessible to the cutter.

Condition

Used (Good Condition / Workshop Worn)

Both clamps are in honest used condition consistent with regular workshop service. The machined surfaces — including the stepped T-slot bases and the serrated toe faces — are intact and functional, with no visible deformation, cracking, or stripping to the threaded bores. The serrations on the jaw faces show normal use wear but retain sufficient tooth profile to grip a workpiece effectively. The body surfaces carry the expected patina of a shop-floor tool: minor surface oxidation, handling marks, and light scuffing to the flanks — none of which affect clamping performance. No box, paperwork, or fasteners are included; you will need appropriate T-slot bolts and nuts to suit your machine’s T-slot width before putting these to work. As with any used workholding, it is good practice to inspect the threaded bores with a thread gauge or test bolt prior to first use to confirm thread integrity.

Included

2 x Strong Tools TC-1B Toe Clamps (105mm × 35mm, 27mm jaw face height)

Not Included

T-slot bolts, nuts, or washers

Mitutoyo 62-75mm Holtest 368-141

Product Overview

The Mitutoyo 368-141 Holtest is a three-point internal micrometer covering the 62–75mm bore range — a workhorse instrument for any toolroom or production floor where accurate bore measurement is non-negotiable. Unlike a two-point bore gauge that relies on a separate dial indicator and master setting, the Holtest reads directly off a calibrated thimble and barrel, giving you a true micrometric reading in one instrument. The three-point contact system self-centres in the bore, eliminating the rocking error that plagues two-jaw internal mics and delivering repeatable readings without operator technique being a variable.

Three-point self-centring contact system — Three tungsten carbide-tipped anvils spread 120° apart locate the instrument on the true centreline of the bore automatically. This removes the need to rock and find the minimum reading as you would with a two-point mic, which means faster measurement cycles and results that don’t vary between operators on the shop floor.
Direct micrometric readout to 0.005mm graduation — Reading directly off the thimble and barrel means no secondary dial indicator to zero, no transfer error from a separate gauge head, and a direct dimensional value you can record or call out without mental arithmetic. For bore tolerances in the H7/H8 range this resolution is more than adequate.
Hardened and ground measuring faces — The carbide contact points resist wear during repeated insertion into bored bores, ground bores, and reamed holes. On a production run of cylinder liners, hydraulic bodies, or bearing housings, this matters far more than it does on a single-off job — the accuracy doesn’t drift mid-run.
Newer-style 368 Series body — The 368 Series uses Mitutoyo’s updated barrel and thimble design with a friction thimble (ratchet stop) for consistent measuring force, keeping readings repeatable regardless of how hard the operator winds in. Setting ring required for zeroing; available separately (see seller note below).
Ideal for — Checking finished bore diameter on turned components on the lathe or machining centre, verifying reamed holes against H7 tolerance, measuring cylinder bores, bearing housing fits, hydraulic valve bodies, and any bored feature in the 62–75mm range where a plug gauge gives pass/fail but you need the actual number.

Condition

(Used — Like New / Well Cared For, Minimal Use)

This Holtest presents in exceptional used condition — about as close to new old stock as a used precision instrument gets. The barrel markings and thimble graduations are crisp and fully legible with no rubbing or wear to the engraving. The carbide measuring faces show no visible pitting, chipping, or flat-spotting under inspection, and the thimble turns smoothly with consistent friction-stop engagement throughout the range — no sticking, grinding, or backlash beyond normal micrometric play. The instrument body carries only the lightest bench patina consistent with careful storage and occasional use; there are no dings, dents, or impact marks to the spindle or measuring head that could indicate a drop or misuse. Functionally, the three contact points extend and retract evenly. As with any used precision instrument, zeroing against a certified setting ring before use is standard practice — a matching setting ring is available separately from the seller, which is the correct way to establish the zero reference on a Holtest regardless of whether it’s new or used. The included calibration certificate provides an additional confidence reference point.

Mitutoyo 87-100mm Holtest 368-143

Product Overview

The Mitutoyo Holtest 368-143 is a three-point internal micrometer covering the 87–100mm range — a workhorse bore measuring tool built for toolrooms and production floors where a two-point bore mic or telescoping gauge simply won’t cut it. Three-point contact self-centres in the bore automatically, eliminating the rocking errors that plague two-anvil designs and giving you a repeatable reading without chasing the axis manually. This is the newer-style Mitutoyo Holtest body — cleaner ergonomics, tighter tolerances from the factory, and a thimble action that reflects the fit-and-finish you expect from Japanese metrology at this level.

Three-point self-centring contact system — Unlike a two-anvil bore mic that requires the operator to find true diameter by rocking, the three-jaw contact system centralises itself in the bore. That means your reading is the actual diameter, not an approximation, which matters when you’re checking a bearing housing to H7 tolerance or verifying a cylinder liner after honing.
0.005mm graduation (5 micron resolution) — At this resolution you’re reading in single-digit microns across the thimble and vernier, which is enough precision to verify interference fits, check bores against a ground ring standard, and catch taper across a bore depth — all without needing a dedicated bench air gauge.
87–100mm measuring range — This range covers common engineering bores: 90mm and 95mm bearing housings, large hydraulic cylinder bores, gearbox and transmission cases, and larger lathe spindle bores. A single Holtest covers 13mm of range, so you’re not swapping anvils mid-job.
Setting ring required for zeroing — A Holtest is zeroed against a calibrated ring gauge, not against itself. The seller notes a setting ring is available separately — if you don’t already have one for this range, factor that into your purchase. Without a traceable ring, you’re relying on the calibration certificate supplied, which is a reasonable starting point but not a substitute for a ground reference at your bench temperature.
Ideal for — Checking bearing housing bores to H7/H6 fit, verifying honed cylinder bores, inspecting gearbox case bores, confirming large chuck register fits, and production inspection of 87–100mm bored components on a machining centre or horizontal borer.

Condition

Used (Like New / Well Cared For)

This Holtest presents in exceptional used condition — the seller describes it as like new and well cared for, and the visual evidence backs that up. The measuring faces and carbide contacts show no visible pitting, scoring, or wear that would affect measuring accuracy. The thimble rotates smoothly with no perceptible slop or drag, and the locking mechanism functions correctly. The newer-style Mitutoyo body is clean with no corrosion, deep scratches, or impact marks to the barrel or frame. Surface finish on the spindle and contact points appears consistent with a tool that has seen careful bench use rather than production floor abuse. The calibration certificate is included, providing a documented accuracy baseline — as with any used precision tool, we recommend verifying zero against a calibrated ring gauge at your working temperature before taking it into a critical tolerance job. A setting ring for this range is available separately from the seller if required.

Mitutoyo 50-63mm Holtest 368-140

Product Overview

The Mitutoyo Holtest 368-140 is a three-point internal micrometer covering the 50–63mm bore range — a workhorse instrument for anyone who needs repeatable, accurate bore measurement without the setup fuss of a two-point bore gauge and setting ring. Unlike traditional two-anvil bore mics, the Holtest’s three-contact design self-centres in the bore, eliminating the rocking technique and reducing operator-induced error. If you’re checking cylinder bores, housing fits, or bushing bores to tight tolerances, this is the instrument that earns its place on the bench.

Three-point self-centring contact system — The tri-anvil head automatically aligns to the bore centreline on insertion, removing the skilled rocking motion required with a two-anvil mic. That means consistent readings between operators and far less chance of measuring a chord instead of a true diameter — critical when you’re holding a fit to a few thou.
0.005mm graduation on a direct-reading thimble — The Holtest reads directly off the sleeve and thimble without conversion or interpolation.
Hardened and ground measuring contacts — Mitutoyo’s contacts are manufactured to tight geometric tolerances and hardened for wear resistance. The spherical contact points minimise cosine error when the tool isn’t perfectly perpendicular to the bore axis — an honest safety net in production environments.
Original Mitutoyo wooden case with accessories included — Ships with the original wooden storage box, spanner wrench, and documentation. Proper storage keeps the measuring faces protected and the instrument ready for calibration checks — not rattling around a drawer.
Ideal for — checking bored housing fits for bearings and bushings, verifying cylinder liner bores, inspecting hydraulic cylinder bores, checking spindle housing bores on lathes and mills, and qualifying bored parts on a machining centre where a two-point gauge would require a master setting ring every session.

Condition

Used (Like New / Minimal Use)

This Holtest presents exceptionally well for a used instrument. The thimble rotates smoothly through its full range with no perceptible backlash or roughness, and the tri-anvil head shows no visible wear, scoring, or corrosion on the contact points — the ground reference surfaces that actually determine your measurement. The barrel and sleeve graduations are clean and fully legible. The body finish retains the vast majority of its original surface with only the lightest handling marks consistent with an instrument that’s been handled carefully and stored properly rather than left on a swarf-covered bench. There is no visible damage, pitting, or impact marking reported by the seller, and nothing visible in inspection imagery that would suggest otherwise. As with any used precision instrument — regardless of cosmetic condition — we recommend verifying zero against a certified ring gauge or a known bore standard before putting it into production work. That’s simply good metrology practice, not a reflection of any functional concern with this specific tool.
