Three‑point internal micrometer M312.462 — 75–88 mm, 0.001 mm reading (Metav IndustryLine)

A three‑point internal micrometer M312.462 engineered for precision measurement of internal diameters and blind holes within the 75–88 mm range.

• 0.001 mm reading resolution
• Range 75–88 mm for internal diameters
• Suitable for blind‑hole measurements
• Includes setting ring and extension rod in case

Precision for fine internal measurements that repeat reliably

The three‑point design provides stable contact with the bore and reduces alignment errors common to two‑point probes, yielding a genuine 0.001 mm reading and an indicated measurement uncertainty of ±0.005 mm. This fine resolution, combined with the matt chrome‑plated scale and vernier, is especially valuable where small deviations matter: calibre inspection, small‑batch production and maintenance tasks that demand traceable results. Classified within the micro range (maximum measuring span up to 100 mm), the instrument is optimised for compact assemblies where stiffness and control are decisive for repeatable results.

Complete accessory set for practical workshop use

Delivery includes an 87 mm setting ring, extension rod (152.4 × Ø23.5 mm) and a protective transport case, ensuring the measuring system is ready for immediate use and secure in transit. The hardened measuring faces preserve contact geometry and extend service life when measuring internal diameters or blind bores, while the overall construction allows single‑person handling when accessibility is constrained. The configuration reduces time spent on set‑up and rework, supporting efficient quality control routines in small parts manufacture.

Durability and traceable handling for everyday metrology

Durable finishes and carefully chosen components make this instrument a pragmatic choice for workshops and inspection benches that require robust, low‑maintenance tools. The three‑point mechanism minimises operator‑induced variation and the matt chrome‑plated scale resists glare for easier reading under shop lighting. Backed by Metav’s quality filter in Emmerich, the device combines practical workshop resilience with the measurement clarity needed to lower scrap rates and speed troubleshooting across mechanical and precision engineering contexts.

FAQ

What measuring range does the instrument cover?
The instrument covers internal diameters from 75 to 88 mm as supplied with the standard setting ring.

What resolution and accuracy can be expected?
A reading resolution of 0.001 mm is provided with an overall stated uncertainty of ±0.005 mm for typical workshop conditions.

Is the micrometer suitable for blind‑hole measurements?
Yes, the three‑point configuration and included accessories are specifically intended for reliable measurement of blind bores.

Which accessories are included with delivery?
Delivery includes an 87 mm setting ring, an extension rod (152.4 × Ø23.5 mm) and a protective transport case.

How does the three‑point system improve repeatability?
The three‑point contact creates a self‑centering effect inside the bore, reducing alignment errors and operator influence on the measurement.
