Three‑point internal micrometer M836.700 — self‑centring, 0.005 mm accuracy (Metav IndustryLine)

A Three‑point internal micrometer M836.700 designed for precise internal diameter checks in fine mechanical and watchmaking applications within the 3.5–4 mm micro range

• Self‑centring three‑point measuring head
• 0.005 mm accuracy for fine inspection
• Analogue dial with 0.001 mm reading resolution
• Suited to internal diameters 3.5–4 mm

Precision tailored to the micro range

This three‑point instrument addresses the demands of the micro range: the compact measuring span of 3.5–4 mm is ideal where short anvils and minimal bending improve repeatability. With a stated accuracy of 0.005 mm and a dial reading step of 0.001 mm, the design focuses on verifiable results rather than approximation. The compact format and solid thimble control make the micrometric measurement chain short and less susceptible to operator‑induced deviation, which benefits tasks such as bore verification in small housings and watch components.

Geometry that improves centring and reproducibility

The self‑centring, three‑point measuring head aligns the instrument automatically with the bore, reducing the need for manual repositioning and lowering operator influence on the result. An analogue mechanism provides tactile feedback during closure, helping to attain consistent contact pressure and a stable reading. The combination of the three‑point contact and mechanical dial gives a predictable measuring behaviour that supports rapid inspection cycles where repeatable internal readings are required.

Practical handling and measurable advantages

Integral measuring faces and a compact frame aid in controlled insertion and removal from small bores without disturbing the part. The mechanical design emphasises ease of handling during repetitive checks, enabling reliable comparative measurements and pass/fail decisions on the shop floor. The instrument’s attributes support workflows where a quick mechanical readout and robust mechanical feel are preferred over electronic systems, while still delivering fine resolution for quality assessment.

Applications, users and trust in delivery

The instrument suits precision workshops engaged in watchmaking, micro‑assembly and small component inspection, where dimensional control of tiny bores is critical. As part of the Metav IndustryLine, the device benefits from a supplier network that positions quality and accessibility side by side; Metav’s practical distribution and product range aim to make precision reachable for specialist and industrial buyers alike. The three‑point internal micrometer is therefore a pragmatic choice for technicians seeking a compact, reliable gauging tool that integrates into established inspection routines.
