Three‑point internal micrometer M836.716 — self‑centring, 70–80 mm range (Metav IndustryLine)

The three‑point internal micrometer is a precision measuring instrument for accurate internal diameter measurement of bores and cavities in workshop and inspection environments.

• Self‑centring three‑point measuring head
• Range 70–80 mm for internal diameters
• Reading 0.005 mm, accuracy ±0.006 mm
• Supplied in protective case

Precision that reduces rework and inspection uncertainty

The three‑point geometry combines simultaneous contact at three opposing points to centre the spindle automatically, offering a self‑centring effect that reduces eccentricity and alignment errors. With a reading of 0.005 mm and a stated accuracy of ±0.006 mm, the instrument delivers the reproducible results required for quality control tasks where small deviations matter. The compact measurement span of 70–80 mm makes this tool well suited to medium‑sized bores commonly encountered in component inspection, while the mechanical design prioritises stable contact and low hysteresis to keep measurement scatter to a minimum.

Built for reliable handling and workshop durability

The construction includes hardened measuring faces, which protect contact areas against abrasive wear and preserve measurement integrity over extended use. The mechanical, analogue display gives a tactile, immediate readout that experienced technicians can interpret without dependence on electronics, simplifying routine checks at the bench. Supplied in a protective case for safe transport and storage, the instrument is prepared for rougher workshop environments and controlled transport to inspection stations, reducing the risk of damage between uses and maintaining calibration stability.

Practical value across production and inspection

Designed as a workshop‑grade inspection tool, the micrometer supports process control by delivering consistent internal diameter checks that help to identify trends before parts leave production. The self‑centring action shortens set‑up time and decreases operator influence on the result, which contributes to fewer measurement‑related rework cycles and more reliable batch acceptance. Where repeatability and straightforward operation are priorities, this three‑point internal micrometer is an effective choice for assembly, machining and maintenance teams who require a robust, repeatable measuring method.
