ABSTRACT:
Adjacent one end thereof the shank of a back spotfacing tool has therein a transverse slot, and a cutter mounting pin which extends between opposite sides of the slot parallel to the shank axis. A cutter has in one end thereof a U-shaped slot which is inserted removably over the pin to support the cutter for limited pivotal movement about the pin into and out of an operative position in which a flat, external, limit surface formed on the side of the cutter remote from the open end of its U-shaped slot engages the bottom of the slot in the shank to support the cutter for a cutting operation, and to prevent removal of the cutter from the pin. The cutter may be swung manually to an inoperative position in which the open end of its slot is positioned to permit removal of the cutter from the pin, or the replacement thereof over the pin.
