Three‑point internal micrometer M312.436 — 25–30 mm, 0.001 mm resolution (Metav IndustryLine)

Three‑point internal micrometer M312.436 for precise measurement of internal diameters and blind bores in workshop and quality‑control environments

• 0.001 mm reading resolution
• Measuring range 25–30 mm
• Hardened measuring faces for durability
• Includes setting ring and extension
• Supplied in protective case

Precision where it counts for production control

The three‑point internal micrometer offers a fine 0.001 mm reading and an indicated accuracy of ±0.005 mm, delivering measurement certainty where small deviations matter. The three‑point design stabilises contact with the bore, reducing centring errors compared with single‑point probes; this results in reproducible internal diameter measurements for batch inspection or setup work. The instrument’s compact measuring range makes it particularly well suited to precision components and fine mechanical assemblies.

Engineered for blind‑hole and internal bore measurement

Designed specifically for blind‑hole measurement, the measuring head and included setting ring (25 mm) allow calibration directly against a traceable reference. The supplied extension (152.4 x Ø15.8 mm) permits access to recessed bores while maintaining measurement stability. With hardened measuring faces, the contact surfaces resist wear, so zero drift and maintenance intervals are minimised — a practical advantage for routine inspection tasks in production.

Robust construction and practical handling

The scale and vernier are matt chrome‑plated, offering corrosion resistance and a low‑glare surface for clear reading. The instrument is supplied in a dedicated protective case, facilitating safe transport and organised storage between measurement tasks. At roughly 1.2 kg, the micrometer balances solidity with manageable handling in the workshop; the build quality supports repeated use without rapid loss of accuracy, making it a dependable tool for quality engineers and precision fitters.

Classification and applicability for workshop standards

With a maximum measuring range of 30 mm, this instrument falls into the micro category of internal gauges, which groups compact devices for fine mechanical work and small bores. The combination of fine resolution and hardened contacts positions the tool for tasks where machinists and quality technicians require trustworthy repeatability rather than broad range. The instrument is therefore appropriate for precision components, small housings and tooling checks in machine shops and component assembly.
