Abstract
An indexable double-negative cutting insert includes an index axis A, two opposing end surfaces, a peripheral side surface which extends therebetween, and opposing side cutting edges formed between the end surfaces and the peripheral side surface. A median plane P is located midway between the end surfaces, passes through the peripheral side surface and is perpendicular to the index axis. The peripheral side surface includes at least one protrusion which extends in an outward direction relative to the index axis, in a plan view of either end surface. The protrusion includes two side abutment surfaces which converge in the outward direction towards the median plane P. In each cross-section perpendicular to the median plane, which cross-section passes through both opposing side cutting edges and also the at least one protrusion, no portion of the peripheral surface is inward of an imaginary line connecting the opposing side cutting edges.
