ABSTRACT:
An on-edge indexable cutting insert in which each end of the insert is formed with a convexly curved surface which gradually decreases in area per unit of length as the curved surface proceeds away from the cutting edges so as to form each cutting edge with a convexly curved tip of relatively large radius while leaving a flat and planar locating surface of substantial area on each end of the insert.
