Digital three-point internal micrometer M312.214 – 16–20 mm, carbide faces (RB6) by Metav IndustryLine

Digital three-point internal micrometer M312.214 for fast, repeatable measurement of small bores and blind holes in workshop and production environments.

• Digital readout with mm/inch and hold function
• Three-point internal measuring for bores 16–20 mm
• Carbide measuring faces for extended wear resistance
• Suitable for blind-hole measurements

Reliable precision for bore measurement

The Digital three-point internal micrometer M312.214 combines a compact measuring head with a three-point contact system to centre consistently in cylindrical bores, reducing eccentricity and operator error. The instrument delivers a declared accuracy of ±0.005 mm, which positions it for fine workshop verification and quality control tasks where repeatable internal dimensions are critical. The three-point geometry stabilises the contact position and minimises tilting, so measurements of bores and blind holes remain reproducible across multiple operators and cycles.

Streamlined digital handling and traceability

A clear digital readout with ON/OFF/SET, HOLD and mm/inch functions accelerates readings and reduces transcription mistakes during measurement routines. The unit supports RB6 data output, enabling direct data capture for logging or SPC workflows and simplifying traceability in production processes. Fast numeric results and a hold function shorten cycle time for repetitive checks and make integration into digital quality systems straightforward, improving process throughput without sacrificing precision.

Built for workshop durability and repeatable results

The measuring contacts are equipped with carbide (HM) faces, offering superior wear resistance for longer service life under frequent use on metallic materials. The instrument is supplied without setting ring and without extension, keeping the tool compact for confined bores while remaining suited to blind-hole measurement tasks. With a lightweight construction and robust contact geometry, the device combines handling ease with long-term dimensional stability, making it a practical choice for mechanical workshops and inspection benches.
