What is a dead length collet?

A dead length collet is a type of clamping device used in machining and manufacturing processes to hold workpieces securely without extending beyond the collet's length. Unlike traditional collets that may allow for some movement of the workpiece, dead length collets maintain precise positioning by ensuring that the workpiece is fixed at a specific length during the machining operation. This design enhances accuracy and repeatability, making them particularly useful in applications like CNC machining and precision assembly.
