A micrometer is widely used in machining and maintenance operations. It precisely measures block thickness, the outer and inner dimensions of shafts, and slot depth. Learning to take accurate readings with a micrometer is critical in precision machining and maintenance work.

The Micrometers online training course introduces common micrometer types, their components, and how to correctly take measurements. It covers outside, inside, and depth micrometers. It also explains reading English scale, metric scale, and vernier micrometers.

This course is part of the Precision Measurement series.
