Abstract

An indexible cutting insert has a connecting surface formed by alternating parallel ridges and grooves. Each ridge is defined by a pair of flanks which converge in an outward direction. Each ridge includes a convexly curved surface portion for making line contact with a corresponding ridge of a support surface. The convexly curved surface is spaced from outer and inner ends of the respective flank.
