Abstract
A die holder comprises a die housing and a guide bar. The guide bar is designed to be retained within a Jacob's chuck retained within a lathe tailstock, and the die housing is slidably movable along the guide bar. A button die is retained within the die housing and with the guide bar aligned with the bar stock workpiece held by the lathe headstock, the die housing may be brought into engagement with the workpiece so that the button die engages the same. A user may then grasp the die holder while the headstock and workpiece are rotating so as to effect a cutting of threads. A reverse rotation of the headstock will result in a disengagement of the die holder.
