This dial indicator is in used condition with visible cosmetic wear (“rough” appearance) on the bezel and body, consistent with a life in a working machine shop. However, it has been tested and is functioning nicely. The spindle action is smooth, the return spring is strong, and the mechanism repeats correctly. It is sold as the Gauge Only (no box or accessories included).
Product Overview
The Mitutoyo 2959S is a specialised “One Revolution” dial indicator designed for error-free reading. Unlike standard indicators that can spin multiple times (leading to counting errors), this model’s measuring range is limited to 1.6mm.
This “One Rev” design effectively eliminates reading mistakes by ensuring the needle never passes the zero point more than once during a measurement. It features a high-sensitivity 0.01mm graduation and a unique shock-proof mechanism to protect the internal gears from sudden impacts. The dial face is balanced (0-100, but effectively sets up as 50-0-50) to clearly show positive and negative deviation from a set zero point.
Brand Information
Mitutoyo Corporation (est. 1934) is the global standard for precision measurement. The 2959S is a favourite in quality control departments because it removes the “human error” factor of miscounting spindle revolutions, making it perfect for Go/No-Go inspection fixtures.

The tracking wheel is a critical component in the Radius Master belt grinding system. Positioned at the top of the machine’s belt head, it works in conjunction with the tensioning and tracking adjustment mechanism to keep the 50 x 1220mm abrasive belt running true — centred, stable, and at consistent tension across all seven grinding stations.
Over time and with heavy use, tracking wheels can develop flat spots, surface glazing, or bearing wear that causes belt drift, uneven tracking, or vibration. Replacing a worn tracking wheel restores the machine’s characteristic precision belt control — the same control that allows the Radius Master to reliably track stiff, heavy-duty polyester-backed ceramic belts that cause tracking problems on lesser machines.
This replacement wheel measures 89mm in diameter x 50mm wide, matching the factory specification of the Series 2 belt head. Being a genuine NIROC/Radius Master part, it fits without modification and maintains the engineering tolerances the machine was designed around.
Signs your tracking wheel may need replacement:
Belt drifts to one side despite tracking adjustments
Vibration or wobble at the top of the belt head
Belt wear pattern skewed to one edge of the belt
Visible flat spots, cracking, or glazing on the wheel surface
Bearing roughness or play when spinning the wheel by hand

Further Information
Genuine Parts vs. Aftermarket
The Radius Master’s ability to track heavy ceramic-backed belts reliably depends on the rubber compound, wheel diameter, and bearing quality of the tracking wheel being within specification. Aftermarket or improvised replacements may use incorrect rubber hardness (durometer) that causes inconsistent belt tension — leading to belt wander, accelerated belt wear, or in worst cases, belt throw. Using genuine NIROC parts keeps your machine operating as designed.
Servicing Your Radius Master
If you are replacing the tracking wheel due to belt tracking problems, it’s also worth inspecting the tracking adjustment knob and tension spring for wear at the same time. NIROC supplies a full range of Radius Master spare parts — contact them directly or visit niroc.com.au for the complete spare parts catalogue.
This Mitutoyo Gauge Block Set is sold in used condition. Prospective buyers must note that the set is incomplete, with four specific blocks missing from the original count:
1.10mm
1.11mm
1.14mm
1.19mm
The remaining blocks show signs of use, which may include surface scuffs, staining.
Product details and use
This is a metric rectangular gauge block set manufactured by Mitutoyo, serving as physical standards for precision linear measurement. The set is designated as Grade 2, historically known as “Workshop Grade.”
Grade 2 blocks are generally intended for use in the workshop environment rather than a temperature-controlled laboratory. They are typically used for setting up machine tools, checking fixtures, positioning workpieces, and calibrating general-purpose measuring instruments like calipers or micrometers where extremely tight tolerances are not required. While incomplete and showing wear, the remaining blocks in this set can still serve as useful references for general shop applications.
Short brand description
Mitutoyo is a world-leading Japanese manufacturer of precision measuring equipment. For decades, they have been renowned for producing high-quality, reliable instruments standard in metrology laboratories and manufacturing facilities globally.
Features
Metric System: Standard metric rectangular blocks.
Grade 2 Accuracy: Suitable for general workshop precision applications and machine setup.
Steel Construction: Manufactured from hardened steel for durability and dimensional stability.
Wooden Storage Case: Includes the original fitted wooden box to organize the remaining blocks.
When you’re measuring the wall thickness of a thin-walled tube, checking the depth of a groove, or verifying the thickness of a disc or flange where a standard anvil micrometer simply can’t get purchase, you need a disc micrometer. The flat, large-diameter disc anvils span bridging features and unsupported surfaces that would rock or slip under a conventional spherical or flat anvil — giving you a repeatable, grounded reading where other mics give you guesswork. The Mitutoyo 169-201 is a 0–25 mm disc micrometer with 0.01 mm graduation, built to Mitutoyo’s JIS-grade toolroom standard, and this unit presents in like-new condition with no visible wear to the measuring faces or thimble graduations.
Large-diameter disc anvils (16 mm diameter, hardened and ground) — The disc geometry distributes clamping load across a broader contact area, critical when measuring thin sheet, non-ferrous strip, or brake disc thickness where a conventional anvil would tip or indent soft material and give a false low reading.
0.01 mm graduation on a clearly engraved thimble and sleeve — The 25-division thimble scale on the 169-201 gives direct readings to one-hundredth of a millimetre. For experienced hands, interpolation to 0.001 mm is practical in a temperature-stable environment, though the stated resolution is 0.01 mm.
Ratchet-stop thimble — The friction-controlled ratchet stop standardises measuring force regardless of operator, reducing the variable most responsible for inconsistent readings when multiple people are working from the same bench setup. This is the feature that separates a toolroom mic from a hardware-store instrument.
Mitutoyo 169-series disc micrometer platform — The 169-201 is the 0–25 mm range variant of Mitutoyo’s dedicated disc micrometer series. No adapters, no third-party disc retrofits — the disc anvil geometry is engineered into the frame from the ground up, keeping parallelism between anvil faces within Mitutoyo’s published tolerance.
Ideal for — Measuring wall thickness of thin-walled tube and pipe, checking brake rotor and clutch disc thickness, verifying sheet metal and gasket material thickness, inspecting disc spring and shim stock, measuring spur gear tooth thickness at the pitch line, and any application where a standard flat or spherical anvil cannot achieve stable contact.
Condition
Used (Like New / Minimal Use, No Visible Wear)
This Mitutoyo 169-201 presents exceptionally well. The disc anvil faces show no visible scoring, pitting, or flat spots — both faces appear clean and bright under inspection, with no corrosion or contact-induced wear marks. The thimble sleeve graduations are crisp and fully legible with no rubbing or paint fill loss. The knurled thimble and lock nut operate smoothly, with no stiction or roughness in the spindle travel across the full 0–25 mm range. The ratchet stop engages cleanly and consistently. The frame retains its original finish with no significant dings, deep scratches, or corrosion — what’s present is nothing more than the expected light handling patina of a tool that has seen careful use. The measuring faces are parallel and the spindle advances and retracts without detectable slop. As with any used precision instrument, verification against a certified gauge block or setting standard before putting it into production use is recommended practice — zero the instrument with the disc faces together and confirm mid-range with a 12.5 mm gauge block or equivalent ground reference to satisfy yourself of accuracy before committing to critical work.

This is a GOST 5641-66 precision V-block and clamp pair, supplied in the original wooden storage box with all hardware. The blocks themselves look virtually unused — only very light superficial marks can be seen under close inspection. These marks are consistent with long-term storage rather than actual workshop use. Both blocks have been kept under a protective lubricant coating, which has preserved the ground faces and V-grooves extremely well. Although they present as new, they are listed as used due to age and prior ownership.
These USSR-era V-blocks were built for layout work, verifying cylindrical parts, machining setups, inspection tasks, and general toolroom use. Their mass, accuracy, and stable geometry make them reliable on the surface plate or on the mill table.
