CNC Collet Chucks

Collet chucks, or collets, are indispensable tools for securely gripping bar stock, particularly in smaller sizes. A collet typically consists of a round steel shell with three evenly spaced slots extending along most of its length. While designs may vary, all collet types function by being compressed around the workpiece, ensuring precise alignment and static friction. These slots impart a spring-like action to the collet, earning them the moniker “spring collets.” The thicker nose of the collet forms the jaws, fitting snugly into the shaped recess of the chuck.
