Three-point internal micrometer M312.161.P — 62–75 mm range, 0.005 mm accuracy (Metav IndustryLine)

The three-point internal micrometer M312.161.P is a precision instrument engineered for reliable measurement of internal diameters and blind-hole bores in a compact, workshop-ready format.

• Three-point contact for self-centring measurement
• High accuracy 0.005 mm for precise fits
• Matt‑chrome scale and vernier for low reflection
• Includes setting ring and extension for blind holes

Accurate blind‑hole measurement with reduced operator influence

The three‑point measuring principle provides self‑centring contact, which significantly reduces alignment error when measuring internal diameters, especially in blind holes. With a verified accuracy of 0.005 mm, this analogue instrument delivers repeatable results for fit and tolerance control in assembly work and quality inspection. The vernier scale is matt‑chrome finished to reduce glare and to support fast, confident readings even under bright workshop lighting.

Built for everyday workshop durability and clear reading

A design focus on robust components ensures low maintenance and long service life. The scale and vernier are matt‑chrome plated, improving legibility and resisting wear, while hardened measuring faces preserve dimensional integrity under frequent use. The compact body and balanced mass provide stable handling; the instrument’s construction minimises flexing to keep measurement uncertainty low and to reduce rework in production.

Ready to measure: accessories and secure transport

The instrument is supplied with a setting ring and an extension (150×Ø21.8) to reach deeper blind bores without losing accuracy. Delivery includes a protective case for transport and safe storage, keeping calibration and setup intact between shifts. These inclusions shorten setup time at the bench and make the device immediately usable for serial checks and setup tasks.

Practical benefits for workshop productivity

Being an analogue three‑point micrometer, the device is free of electronic interfaces yet provides industrial‑grade accuracy and tactile control that many technicians prefer for hands‑on inspection. The combination of high resolution, rugged measuring faces and practical accessories translates into fewer measurement cycles and faster go/no‑go decisions on the shop floor.

FAQ

How does the three‑point contact improve centring compared with two‑point tools?
Three equally spaced contact points automatically centre on the bore, so the three‑point internal micrometer M312.161.P reduces positioning errors and gives a stable reference for repeatable measurements.

Can this instrument measure blind holes reliably?
Yes — the design and included extension are tailored for blind‑hole measurement, allowing accurate access and repeatable readings for bore depths within the specified range.

What accuracy and resolution can be expected during normal use?
The device provides a resolution and accuracy of 0.005 mm, suitable for precision fitting and inspection tasks where tight tolerances are required.

What is included with delivery?
Delivery comprises the micrometer, a setting ring, the stated extension (150×Ø21.8) and a transport case to protect the instrument in transit and storage.
