5C Collet
A popular collet used on many lathes and workholding devices is the 5C collet.

Some 5C collets have an internal thread that allows work positioning fixtures to be installed.

5C collets are tightened on the workpiece by pulling on the threaded exterior of the collet. This force pulls the taper against a tapered bore and forces the collet fingers against the workpiece.
