Three-point internal micrometer — Self-centring three-point design, 40–100 mm range (Metav IndustryLine)

A three-point internal micrometer designed for precise bore measurement in workshop and inspection environments, offering a standard-range solution for routine engineering tasks.

• Self-centring three-point measuring principle
• Measurement range 40–100 mm
• Resolution 0.005 mm for fine reading
• Supplied in protective case, set of 6

Consistent bore measurement for production and inspection

The three-point internal micrometer delivers repeatable internal diameters thanks to its self-centring measuring head and consistent contact geometry. The instrument is tailored for the standard measurement class (max. 100 mm), which balances reach and rigidity for everyday tasks in Machine and Metalwork. With a reading increment of 0.005 mm and an indicated accuracy of 0.006 mm, the device supports quality-control processes where tight tolerances and traceable repeatability are required. The three-point principle reduces the influence of off‑axis alignment, making readings more dependable on cylindrical and stepped bores.

Robust contact surfaces and practical adjustment options

Hardmetal measuring faces ensure long-term wear resistance and stable measurement results on typical workshop materials. The set includes setting rings at 50, 70 and 90 mm, enabling quick calibration across the working range and straightforward verification of the measuring chain. The analogue spindle and thimble mechanism give tactile feedback for fine positioning, while the compact construction aids ergonomic handling during repetitive checks. The combination of carbide faces and precise setting accessories reduces downtime for recalibration and keeps inspection cycles efficient.

Designed for workshop efficiency and secure storage

Delivered as a set with six pieces and protected in a transport case, the kit is arranged for fast selection and safe storage between shifts. The compact standard range size supports one-handed guidance without sacrificing stiffness, helping to maintain measurement integrity across multiple operators. For integration into established inspection routines, the instrument’s mechanical design minimises the need for frequent service while offering immediate visual confirmation of size changes. The product thus contributes to a streamlined production flow and reliable dimensional documentation.

FAQ

What measurement range is covered by this three-point internal micrometer set?
The set covers internal diameters from 40 to 100 mm, making it suitable for standard workshop and machine‑building inspection tasks.

Is the instrument suitable for routine quality control in a production line?
Yes, the Metav IndustryLine three-point internal micrometer (SKU M836.750) offers a resolution of 0.005 mm and an indicated accuracy of 0.006 mm, which supports routine quality-control checks and repeatable measurements.

How are calibration and setting handled for the micrometer?
Calibration is performed using the supplied setting rings (50, 70, 90 mm) and the extension option of 150 mm; these accessories permit quick in‑house verification of the measuring chain.

Are the measuring faces durable enough for workshop use?
The measuring faces are made of hardmetal (carbide), which provides high wear resistance and long service life under normal workshop conditions.

Can this instrument be used on stepped bores and standard cylindrical bores?
The self-centring three-point design is optimised for both cylindrical and stepped internal geometries, improving centring and repeatability in typical bore inspection applications.
