A polygonal indexable cutting insert including a pair of faces, a plurality of peripheral side surfaces, a plurality of rounded corners, a plurality of cutting edges formed with an edge radius, a plurality of triangular-shaped areas proximate the rounded corners; and a plurality of chip breaking scallops positioned along the cutting edges. Each scallop has a bottom surface formed by a rake face and an arcuate back wall having a varying depth. The arcuate back wall of each scallop intersects the arcuate back wall of adjacent scallops at a point located at a distance from each cutting edge for providing a wedge effect that facilitates in dividing and breaking chips.
