Abstract:
1. A tangential cutting insert, for use in a milling cutter, comprising: two identical opposing end surfaces of a generally rectangular shape in an end view of the cutting insert; a peripheral side surface extending between the two opposing end surfaces, the peripheral side surface comprising two identical opposing major side surfaces of a generally parallelogrammatic shape, two opposing minor side surfaces and corner side surfaces located between adjacent major and minor side surfaces; and a peripheral edge formed at the intersection of each end surface and the peripheral side surface, two sections of each peripheral edge constituting cutting edges; each end surface having four corners, two diagonally opposed lowered corners and two diagonally opposed raised corners, the lowered corners being closer to a median plane M of the cutting insert than the raised corners; each cutting edge comprising a major cutting edge formed by the intersection of a given major side surface with a given end surface; each end surface being provided with an abutment member having an abutment surface; wherein, in each cross section of the cutting insert taken in a plane that is parallel to a minor plane P wherein the end surfaces differ in shape from both the minor side surfaces and the major side surfaces.
