Patent ID: 7104735

Claim:
A tangential cutting insert for use in a milling cutter, comprising: two identical opposing end surfaces, each end surface having a generally rectangular shape in an end view of the cutting insert; 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, the median plane M being located between the opposing end surfaces; 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 connected to two opposing minor side surfaces; and a peripheral cutting edge formed at the intersection of each end surface and the peripheral side surface, each peripheral cutting edge including major cutting edges formed at the intersection of the major side surfaces and with an end surface; wherein each end surface comprises four separate planar abutment regions, none of the four planar abutment regions being parallel to the median plane M.
