ABSTRACT:
A die head has replaceable radially slidable threading dies moved by a bushing with cams. As the workpiece is threaded to the desired length, its end contacts cam surfaces which move a sensor bolt and a control pin to disengage the bushing from a locked position. The bushing can then move axially to radially retract the threading dies from the workpiece.
