ABSTRACT:
An indexable cutting insert having a polygonal body including top and bottom surfaces connected by a peripheral wall having sides and corners. In a generally diamond shaped embodiment, opposite acutely angled corners and the adjacent sides form cutting edges at their junctures with the top surface, forming noses at the corners. A narrow cutting land extends inward from each cutting edge and slopes downward from the nose along both adjacent sides. A chip groove includes a pair of wedge faces, sloping downwardly from the cutting land to a flat floor and a radius blend juncture aligned with the nose and bisecting the adjacent sides. A pair of chipbreaker faces slope upward from the flat floor and backward from a ridge that connects the chipbreaker faces and is upwardly aligned with the juncture of the cutting faces. Various additional features are also disclosed.
