Mitutoyo 3058F — 80mm Long-Range Dial Indicator, 0.01mm Graduation
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.

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.
