Insize Shank Runout Tester

A shank runout tester is a precision tool used to measure the radial deviation or "runout" of a tool shank, such as those used in milling machines or lathes. This deviation can affect the accuracy and quality of machining operations. The tester consists of a sensitive dial indicator mounted on a stand, with a V-block or similar support for the tool shank. The shank is rotated, and the dial indicator measures the amount of radial movement, indicating the runout. Shank runout testers are crucial for ensuring the proper performance of machine tools and are used in manufacturing, tool and die making, and precision machining industries.
