ABSTRACT:
An improved bit-like device for proper removal of spot weld interconnections of upper and lower flat members, such as in sheet metal operations. The device includes an outer member sleeved over a bit shank, rotational and slidable connection structure between the outer member and the shank, a spring biasing the outer member to a non-work position, and stop members, preferably adjustable, to limit the relative axial movement of the outer member with respect to the shank and thereby limit the depth of metal removal.
