Pistol‑style three‑point internal micrometer set (M312.325.O) — digital, Bluetooth, 12–20 mm (Metav IndustryLine)

The Pistol‑style three‑point internal micrometer set delivers rapid, self‑centring diameter checks for small bores and blind holes in the 12–20 mm range and is supplied as a ready‑to‑use set with two exchangeable heads

• Pistol‑style ergonomic design
• Measurement range 12–20 mm
• Resolution 0.001 mm digital display
• Bluetooth data output for traceability

Rapid, repeatable bore measurement for production use

The set is engineered for efficient internal diameter control in workshops and small‑batch production. The three‑point measurement principle centres automatically in the bore, reducing positioning errors and enabling consistent readings even in blind bores. The pistol grip and compact balance simplify one‑hand operation, shortening cycle times and minimising operator fatigue. With a measurement range of 12–20 mm and exchangeable heads covering sub‑ranges, the instrument is tailored to precision work on small components while remaining robust enough for routine inspection tasks.

Traceable digital output and precise metrology

A high‑resolution digital read‑out with 0.001 mm steps and a stated accuracy of ±0.004 mm supports stringent quality requirements and enables reliable pass/fail decisions. The display offers ON/OFF, SET, HOLD and mm/inch/MODE controls for flexible measurement workflows. Integrated Bluetooth output permits direct data transfer to inspection software or SPC systems, reducing transcription errors and ensuring measurement records are available for traceability and process control. The digital interface transforms manual checks into a documented part of the quality chain without complex retrofitting.

Practical design and kit contents for workshop efficiency

Delivered as a complete set, the package includes one pistol‑style measuring body and two exchangeable measuring heads, allowing quick adaptation between the supplied sub‑ranges. Hardened measuring faces are provided for durable contact and repeatable performance in typical shop conditions. The instrument’s pragmatic design balances stiffness and ergonomics: the pistol form eases access to recessed bores while the three‑point contact gives a reliable datum even on imperfect surfaces. For operators accustomed to mechanical gauges, the familiar tactile feel is retained alongside digital convenience.
