Three‑point internal micrometer M836.725 — self‑centring, analogue precision (Metav IndustryLine)

The Three‑point internal micrometer M836.725 is an analogue internal measuring instrument designed for accurate diameter measurement of bores and reamed holes in standard workshop and production environments.

• Self‑centring three‑point measuring system
• Analogue display with 0.005 mm scale
• Accuracy ±0.012 mm for repeatable results
• Carbide measuring faces; durable contact surfaces

Reliable internal measurement for everyday workshop needs

The instrument is engineered as a standard‑range internal micrometer covering a measuring span from 250 to 275 mm, placing it firmly within the workshop lengths most frequently used in metalworking and tooling. The self‑centring three‑point mechanism ensures the contact points align automatically with the bore, reducing setup time and eliminating centring errors common with simpler gauges. Thanks to the carbide measuring faces, contact wear is minimised and measurement stability is maintained under repeated use, which supports consistent quality control without frequent reconditioning.

Clear analogue reading with industrial accuracy

An analogue scale with a reading step of 0.005 mm combines tactile control with a resolution fit for precise checks; the instrument’s stated accuracy of ±0.012 mm provides a reliable tolerance band for typical machining and inspection tasks. The vernier‑style readout suits environments where battery‑free, robust operation is preferred and where a direct, unambiguous visual confirmation of the result is required. For users migrating from calipers or bore gauges, the mechanical feedback of an analogue instrument aids repeatable application of measuring force and supports hands‑on quality routines.

Built for production use and straightforward handling

Designed for routine use in machine shops, toolrooms and inspection benches, the tool’s geometry balances reach and rigidity for measurements across medium‑sized components. The micrometer is supplied in a protective case for transport, simplifying on‑site handling and storage between inspection cycles. Its construction supports rapid checks during set‑up and serial inspection, reducing process interruptions and helping maintain steady throughput on the shop floor.

FAQ

What measuring range does this internal micrometer cover?
The three‑point internal micrometer M836.725 covers a range of 250–275 mm, suitable for standard workshop measurements within that span.

How precise is the analogue reading on the instrument?
The analogue scale provides a 0.005 mm reading step and the device is specified with an accuracy of ±0.012 mm for repeatable checks.

Are the measuring faces durable for frequent use?
Yes, the tool is fitted with carbide measuring faces, which resist wear and give stable contact behaviour during serial inspections.

Is the micrometer self‑centring and how does that help?
The self‑centring three‑point system centres automatically within the bore, reducing alignment effort and improving repeatability compared with two‑point setups.

How is the instrument delivered for safe handling?
The micrometer is supplied in a protective transport case (plastic or wooden), which simplifies storage and transport between inspection points.
