In what increments is the thimble on an outside micrometer divided?

The thimble on an outside micrometer is divided into increments that allow for precise measurement of small distances. Specifically, the thimble typically features a graduated scale that is marked in 10 increments for every full rotation. Each increment generally corresponds to a specific measurement, such as 0.01 inch or 0.01 mm, depending on the micrometer's calibration. This design allows the machinist to take very accurate measurements by reading both the main scale and the thimble scale, providing a total reading with high resolution. This is vital in machining and manufacturing environments, where precision is critical for maintaining quality control and tolerances in parts and assemblies.
