Digital three-point internal micrometer M312.222 (87–100 mm) – RB6, carbide faces

A Digital three-point internal micrometer M312.222 for precise measurement of internal diameters in blind holes, designed for repeatable workshop and inspection use in the 87–100 mm range.

• Digital readout with mm/inch and hold
• Carbide measuring faces for wear resistance
• Accuracy ±0.005 mm for high-precision measurement

Precise blind‑hole measurement with repeatable results

The three‑point measuring principle provides concentric contact around the bore, yielding more stable readings than single‑edge probes; combined with the RB6 spindle system this reduces eccentricity errors when assessing blind holes. Delivering a resolution of 0.001 mm and an accuracy of ±0.005 mm, the instrument is suitable for quality control tasks where reproducibility matters. The digital readout with ON/OFF/SET and HOLD functions allows quick capture of values and straightforward unit switching between mm/inch, simplifying documentation during inspection rounds.

Durable construction for production environments

Carbide (HM) measuring faces ensure long service life even under frequent use, maintaining measurement integrity when checking components made from a variety of materials. The robust build contributes to stable contact pressure and repeatable results; this is particularly beneficial when checking series‑produced parts or jigs. The design supports efficient measurement workflows by reducing the need for frequent rechecks and thus contributes to measurable time savings on the shop floor.

Easy integration into inspection routines

Equipped with a clear digital display and essential control keys, the instrument fits into standard workshop routines without elaborate setup. The instrument is tailored for blind‑hole measurement and marked by practical ergonomics for single‑handed operation where applicable. Traceability is supported through clear numerical output, and the unit’s specifications make it a reliable choice for machinists and inspection staff who need fast, precise readings as part of incoming‑goods checks, in‑process control or final inspection.
