Abstract
A cutting insert has two opposing end surfaces interconnected by a peripheral side surface, the peripheral side surface having two major side surfaces and two minor side surfaces. Major edges are formed at the intersection of the major side surfaces and the end surfaces. Each end surface has two diagonally opposed raised corners and two diagonally opposed lowered corners with respect to a median plane, each raised corner adjoining one of the major edges at a first major point and each lowered corner adjoining one of the major edges at a third major point. In a major side view, each major edge has an associated first imaginary straight line containing its first and third major points, and an elevated edge portion located on one side of the first imaginary straight line. The cutting insert is removably secured in a rotary cutting tool.
