Abstract

An assembly that includes a rotatable cutting tool and a tool holder. The rotatable cutting tool has an integral enlarged dimension portion mediate which has a periphery and a rearwardly facing surface which defines a generally planar shoulder. The tool holder includes a bore and has an integral mating surface which surrounds the forward end of the bore. The mating surface has a peripheral edge. The rotatable cutting tool is rotatably retained in the bore of the tool holder body so that the shoulder of the elongate cutting tool body contacts the mating surface of the tool holder body and the periphery of the enlarged dimension portion of the elongate cutting tool body extends radially outwardly past the peripheral edge of the mating surface.
