Key Features & Benefits
- Three mics covering 0–75mm — the everyday workshop outside-measurement range from M3 fasteners through to 75mm turned stock in one kit.
- Tungsten-carbide measuring faces — each mic’s anvil and spindle faces resist wear from repeated contact on hardened steel.
- 0.01mm graduation with ratchet stop — thimble reads to 10µm; the ratchet applies consistent measuring pressure so readings don’t vary with operator grip.
- Setting standards included — verify zero on each mic against the supplied reference standard before critical readings.
- Locking clamp on each mic — lock the spindle at a dimension for transfer to another caliper or part.
- Fitted carry case — protects the three mics and their setting standards; keeps the kit organised in the tool cabinet.
When to Use the AC-321-003-03 Set
This set is the essential starter kit for a new machinist, apprentice tool chest or QC bench — three mics covering the everyday measurement range in one purchase at significantly lower cost than three individual mics. For specialised needs step up to the AC-313 IP65 digital mic for coolant environments, the AC-352 inside mic set for bores, or the AC-391 depth mic for hole/shoulder depths.
Pro Tip: Calibrate each mic in the set against its supplied setting standard when you first unbox, then again every six months or after any drop — a mic with a 0.01mm calibration offset reads consistently wrong, and the offset is invisible without a reference check. Logging the date of each calibration in a small notebook in the case tracks drift over the kit’s life.
