ABSTRACT:
A double-sided insert includes upper and lower rake faces. The rake faces include chip faces lying on the uppermost and lowermost planes of the insert to respectively define a chip deforming face and a holder-engaging supporting face. Those rake faces are so located that the rake face(s) serving as a support face(s) is disposed closely adjacent the cutting edge to minimize stresses imposed on the insert during a cutting operation.
