ABSTRACT:
Holes are cut in a metal workpiece by means of an annular cutter. The chips formed are broken and prevented from wrapping and accumulating around the cutter and its arbor by means of a chip breaker in the form of a lug or plate positioned generally radially to the cutter and extending into close proximity with the outer periphery of the cutter.
