ABSTRACT:
A cutting insert for use with a rotary milling cutter tool has at least one major cutting edge comprising first, second and third successive component cutting edges. Each second component cutting edge is substantially coextensive with the bore and is of substantially greater length than the length of each of the first and second component cutting edges, and defines with respect to the axis of rotation of the cutter tool an axial rake angle which is substantially less positive than the axial rake angles defined respectively to the first and third component cutting edges with respect to the axis of rotation.
