ABSTRACT:
A collet rotatably mounted in the tool bracket of a Swiss-type automatic screw machine is assembled with a mechanism for contracting the collet to grip the work with sufficient force to cause the collet to rotate with the work but yet enable the work to translate axially through the collet as it is advanced or retracted by the rotating head stock of the screw machine.
