Three‑point internal micrometer M312.430 — 6–8 mm, 0.001 mm resolution

The three‑point internal micrometer M312.430 is a workshop instrument for precise measurement of blind‑hole bores in the 6–8 mm range, supplied with a setting ring and an extension and presented in a protective case.

• Three‑point internal measuring system
• Resolution 0.001 mm for sub‑micron checks
• Delivered in protective case with extension
• Suitable for blind‑hole bores 6–8 mm

Precise internal measurement tailored to blind holes

The three‑point design offers a stable contact geometry that minimises tilting and gives a reliable indication when measuring recesses and internal bores. With a measuring range of 6–8 mm and a readout of 0.001 mm, this instrument provides fine graduations for demanding checks, while the stated accuracy of ±0.004 mm ensures measurements are meaningful for quality control and tool setting. The matt‑chrome plated scale and vernier enhance contrast and reduce reflections for easier reading in workshop lighting.

Easy setup and secure handling in production

A dedicated setting ring is included to establish a repeatable zero point, reducing setup time during serial inspections. The supplied extension (101.6 x Ø5.8 mm) allows access to deeper blind bores without compromising stability. For transport and storage, the device arrives in a protective case, protecting delicate measuring faces and ensuring the instrument is workshop‑ready straight away; this combination reduces downtime and improves throughput in repetitive inspection tasks.

Practical benefits for craft and industry

Designed for users who require compact, accurate internal measurement—toolmakers, maintenance teams and production inspectors—the micrometer balances precision with robustness. The three‑point contact reduces operator influence compared with single‑point probes, supporting routine reproducibility and faster decision‑making on the shop floor. As an entry in Metav IndustryLine, the instrument aligns with a supply chain that emphasises consistent quality and reliable availability for European workshops.
