Three‑point internal micrometer M312.132.P — 10–12 mm, blind‑hole measurement, Metav IndustryLine

The three‑point internal micrometer is a precision gauge designed for tight‑space bore measurements and blind‑hole inspection in workshops and production environments

• Three‑point internal measuring system
• Suitable for blind‑hole bores
• Measurement range 10–12 mm
• Accuracy ±0.004 mm

Exceptional accuracy for small‑bore inspection

The instrument delivers accuracy ±0.004 mm, offering a measurable reduction in rework and quicker in‑process checks compared with less precise tools. Its three‑point contact head centres itself in the bore, which improves reproducibility on cylindrical interiors and minimises angular errors that occur with single‑point probes. Combined with a fine vernier reading (0.001 mm), the gauge supports consistent quality control routines where small tolerances are decisive.

Robust design and ready‑to‑use delivery

A matt‑chrome scale and vernier provide durable, low‑glare markings that remain legible under workshop lighting. The gauge is supplied complete with a setting ring and an extension (50 mm × Ø5.7 mm), so the measuring setup can be adjusted for slightly recessed or awkward bores without improvised workarounds. The complete kit is delivered in a protective transport case to reduce the risk of damage in transit and storage, supporting reliable availability on the shop floor.

Practical measurement workflow that saves time

The three‑point contact reduces the need for repeated repositioning: insert, seat the head, and read the result from the vernier — the typical workflow that cuts inspection time. The included setting ring allows verification of the instrument zero and fast on‑machine checks, while the extension adapts the instrument for deeper blind holes. Together these features provide a pragmatic balance of speed, repeatability and hygiene for serial inspection tasks.

Who benefits and where it belongs

This compact internal micrometer suits machine shops, toolrooms and maintenance departments that regularly inspect small bores, housings and valve seats. It is particularly useful for mould‑making and precision assembly work where a reliable blind‑hole measurement is required without sacrificing portability. The instrument’s straightforward mechanical design makes it a pragmatic choice for routine production checks and spot sampling.
