Description
Product Overview
Finding edges, locating hole centres, and setting tool Z-heights on a CNC or manual mill is the kind of task where a 3D probe saves genuine time and eliminates the guesswork of wigglers and paper-feel methods. The BIG Daishowa 3D Master 3DM-10A is Japan’s answer to probing done right: a single mechanical 3-axis touch sensor that reads X, Y, and Z deflection on a large, easy-to-read dial gauge — unlike wiggler-style edge finders that only work on one axis, or electronic probes that tie you to a specific machine’s probing system. Chuck it in a 10mm collet, wind down, and you’ve got sub-hundredth repeatability in all three directions on any machine that’ll hold the shank. Ideal for tool setters, jobbing shops, mould makers, and anyone who values accurate probing without the cost of a Renishaw installation.
- True 3-axis mechanical probe — reads X, Y, and Z deflection on a single large analogue dial, no electronic interface required.
- 0.01mm graduation with repeatability typically under 0.01mm — genuine production-grade accuracy for edge finding and centering.
- Works on any material including non-conductive workpieces (resin, ceramic, coated parts) — no need for electrical conductivity like entry-level electronic edge finders require.
- ±4mm XY stroke and 4mm Z stroke — generous over-travel protects the probe from light crashes and lets you ride into position confidently.
- 10mm straight shank fits directly into any 10mm collet chuck (ER, TG, straight collet), or a 10mm milling holder.
- Compact body design avoids interference with workpiece geometry in tight setups.
- Ideal for CNC and manual mill setup, mould and die work, edge finding on non-conductive materials, hole and boss centre-finding, Z-height setting, and tool-setter duty.
Condition
Used (Like New Gauge / Cosmetic Gouge on Body — Pictured).
Full transparency on this one, as the damage is visible in the listing photos:
The good news: the 3D Master itself presents as virtually new — the stylus is straight, the dial gauge face is clear and unmarked, and the probe operates cleanly in all three axes with expected smooth motion and accurate return-to-zero. Testing confirms the gauge is working correctly and reading accurately; consistent with the tool having seen relatively little actual use.
The honest disclosure: there is a visible gouge on the body housing, caused by a previous operator crashing the tool into a workpiece (pictured in the listing). The damage is cosmetic — it’s on the outer body and does not affect the probe mechanism, the stylus, or the reading accuracy. Any experienced toolroom operator will recognise this as the “it happened once, to everyone” kind of battle scar that comes with probe ownership. Nothing to compromise the tool’s function; just something to be aware of before purchase. The fact you can pick up a genuine 3DM-10A at used-tool money rather than full retail is the practical upside here.
The original box shows its age — dusty and grubby from storage — but the tool inside is what matters.
Included:
- 1 x BIG Daishowa 3D Master 3DM-10A (10mm shank)
- Original ball-end stylus
- Original storage box (dusty, used condition)
Brand Information
BIG Daishowa (also sold as BIG KAISER in Europe/US) is one of the most respected names in precision tool-holding and machine setup instruments globally. Founded in Osaka, the company has become the de-facto standard for high-end tool holders, collet chucks, and setup tools in premium CNC shops worldwide. Their 3D Master is widely considered the benchmark mechanical 3-axis probe — copied by many, matched by few. Buying a genuine BIG Daishowa probe means you’re getting the real stylus geometry, bearing quality, and repeatability that the brand’s reputation is built on.
