ABSTRACT:
A tangential milling cutting insert having two identical opposing end surfaces with two identical opposing major side surfaces of a generally isosceles trapezoidal shape and two identical opposing minor side surfaces extending between them is disclosed. Each end surface has a peripheral edge containing cutting edges and four corners of which two diagonally opposed corners are lowered and the other two are raised. Each end surface is provided with an abutment member having an abutment surface. In each cross section of the cutting insert taken in a plane parallel to a minor plane of the cutting insert, the abutment surface is closer to a median plane than a respective leading section of a major cutting edge.
