Condition

New & Sealed.

Product Overview

The Mitutoyo 368-163 is a high-precision “Holtest” (Hole Test) internal micrometer designed for the accurate measurement of small bores between 10mm and 12mm. Unlike standard 2-point inside micrometers, this instrument utilises a three-point self-centring action, which ensures the tool is perfectly aligned with the axis of the bore for stable and repeatable measurements. The contact points are coated in Titanium Nitride (TiN), a gold-coloured hard coating that offers superior wear resistance and durability compared to standard steel faces. This model is also capable of measuring close to the bottom of blind holes, making it an invaluable tool for complex machining and inspection tasks. It features a ratchet stop mechanism to ensure a constant measuring force, preventing variations in readings caused by different operator techniques.
