Internal 3-Point Micrometer 16-20mm

The 3-point inside micrometer is an excellent choice for accurate inside diameter measurements, whether for inside, through, or bottom hole measurement. The instrument is supplied in a handy aluminum case – ready to use immediately. The micrometer's three carbide measurement points ensure reliable, concentric, and repeatable measurements even in deep holes. In addition, the integrated friction mechanism ensures that the measuring force remains constant, resulting in stable and accurate measurements. This inside micrometer is suitable for machine shop, workshop, and measurement laboratory use, where accurate and repeatable inside diameter measurement is desired. Easy to use and precise — an excellent tool for monitoring small inside diameter tolerances.
