Description
Product Overview
When you’re stacking blocks to set a sine bar, qualifying a surface plate, or dialling in a precision ground stop on your mill table, your entire measurement chain is only as good as the reference you start with. A worn slip gauge or a borrowed block of unknown grade poisons every measurement downstream — and that’s the problem a quality gauge block set exists to solve. This Mitutoyo 32-piece metric gauge block set gives you a verified, wrung-able stack of hardened steel references covering the critical range from 1.005mm through to 60mm, letting you build virtually any combination dimension right at the bench without reaching for a calculator and a pile of compromises. The set presents in its original wooden storage case with no rust on any block — a meaningful baseline for a used set of this type.
- Hardened steel gauge blocks with lapped and ground reference faces — the wringing action between blocks depends entirely on surface finish quality; these Mitutoyo blocks exhibit the flat, reflective faces that allow proper molecular adhesion when wrung, confirming the lapping has held up through prior use.
- 32-piece coverage spanning fine increments through large steps
- Original Mitutoyo wooden presentation case — the labelled wooden tray keeps every block indexed in its correct slot, critical for a gauge block set where a missing or swapped block can silently corrupt your stack combinations; the case shows age-appropriate wear but remains fully functional as a storage and organisation system.
- Ideal for — zeroing and qualifying height gauges, building sine bar angles, setting up precision stops and depth references on milling machines and surface grinders, calibrating comparators and dial indicators against a known standard, and toolroom inspection work where a traceable dimensional reference is required at the bench.
Condition
(Used — Good Condition / No Rust, Grade Unknown)
The gauge blocks present well for a used set. Visually inspecting the image, the working faces of the blocks across all rows are free of rust, pitting, or visible corrosion — the surfaces retain their characteristic silver-grey ground finish without the orange staining or surface bloom that makes a gauge block set unserviceable. The wooden case interior shows honest age: the fabric lining in the lid has accumulated some surface soiling and light marking consistent with workshop storage, but the block slots in the tray are intact and each block seats correctly in its labelled position. The seller has confirmed no rust and workshop-ready condition, which aligns with what the photograph shows.
The one transparency item that must be called out: the grade label has worn off, so the original accuracy grade — whether this set left the factory as Grade 0, Grade 1, or Grade 2 — cannot be confirmed from documentation. Mitutoyo manufactured sets at multiple grades, and without calibration paperwork or the original label, you are buying an unknown-grade set. For toolroom inspection or quality-critical metrology requiring traceable accuracy, this set should be calibrated against a certified master or sent through a calibration laboratory before use in a formal inspection context. For shop-floor use — zeroing height gauges, setting up comparators, building sine bar stacks to working tolerances, or establishing reference dimensions for machining setups — the condition of the surfaces and the absence of damage mean this set will perform reliably within the accuracy expectations of typical workshop practice. If in doubt, wring the blocks together and check for proper adhesion; blocks that wring cleanly and hold are telling you the faces are flat and in usable condition.

Brand Information
Mitutoyo Corporation, founded in Japan in 1934, is the benchmark name in precision metrology across the global toolroom and manufacturing industry — sitting at the same tier as Tesa, Carl Zeiss, and Starrett when it comes to dimensional measuring instruments. Their gauge blocks are manufactured to exacting Japanese industrial standards with hardened steel and precision-lapped faces, and the brand is the reference choice in Australian toolrooms, technical colleges, and aerospace and defence manufacturing facilities. A used Mitutoyo gauge block set retains credibility that generic or unbranded blocks simply cannot match, because the manufacturing tolerances and material quality were correct from day one.
