ABSTRACT:
A bar stock puller for advancing bar stock in a machine tool including a tool body having a shank engageable by a tool holder and a jaw support portion pivotally mounting a pair of jaw assemblies that define spaced, opposed jaws adjustably mounted to a pair of jaw holders. The replaceable jaws define V-shaped, confronting gripping surfaces for engaging the circumference of substantially round bar stock and are biased towards each other in a clamping direction by a spring biasing force applied to the jaw holders by a plunger and an adjustable spring located within the shank. The jaw holders also define recesses which together define a gauge receiving opening by which the bar puller can be preset for a particular bar stock size at a location remote from the machine tool.
