This RS PRO micrometer set is used to measure internal diameters. The storage case contains a micrometer head, four extension tubes ranging from 13 mm to 100 mm in length, a setting piece and adjustable tools.
The micrometer's barrel has a non-glare satin chrome finish, which means you can easily read measurements in a wide range of lighting conditions. Engineers have designed and tested this set for quality and accuracy. Internal micrometers like this one are commonly used for measuring bearing clearance, as well as the inside of tubes and pump casing wearing rings.
