Product Overview

The Mitutoyo 468-168 Digimatic Holtest is a three-point internal micrometer designed for high-precision measurement of bores in the 30–40 mm range. Featuring titanium-nitride coated contact points and a self-centring design, it provides durable, wear-resistant performance with reliable accuracy in both through holes and blind bores.

The large digital LCD display allows fast, easy-to-read results with 1 µm resolution, while the ABSOLUTE encoder retains the origin point even after power-off. This model is SPC-compatible, making it suitable for inspection and production environments where data logging is essential.
