Description
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.

Brand Information
Mitutoyo Corporation, founded in Japan in 1934, is broadly regarded as the global benchmark in hand-held precision metrology. Their instruments are manufactured to JIS and ISO standards in facilities that supply calibration-grade tooling to aerospace, automotive, and defence industries worldwide. In the Australian trade, Mitutoyo sits firmly in the top tier alongside Mahr and Tesa — a clear step above general-purpose import brands and, for most machinists, the reference point against which other indicators are compared. Made in Japan is not marketing copy here; it’s a meaningful quality indicator that reflects material selection, manufacturing process control, and long-term reliability in the field.
