Abstract
An indexable cutting insert includes a top surface, a bottom surface, a plurality of peripheral side surfaces, and a plurality of cutting edges formed at an intersection between said top surface and plurality of side surfaces. A plurality of triangular-shaped serrations are positioned along the cutting edges, each serration comprising an apex and a pair of side surfaces that meet at a vertex. The serrations provide the cutting edges with both a positive axial rake angle and a negative axial rake angle, thereby reducing delamination when machining a composite material.
