ABSTRACT:
A milling cutter includes a generally cylindrical body whose outer periphery is formed with angularly spaced pockets capable of accepting indexable cutting inserts of various shapes such as octagonal inserts, square inserts or round inserts. The cutting face of each insert defines a single shallow frusto-conical surface in order to impart a gradual curvature to the cutting edges. This geometry, together with the geometrical location of the inserts in the body, enables the cutter to cut in an extremely free manner and with high efficiency.
