Abstract
A cutting insert includes a body having an upper face, a lower face, a plurality of planar flank faces, bidirectional acute cutting corners and bidirectional obtuse cutting corners joining two adjacent flank faces. A land has a varying width. An annular island includes a plurality of bulged extensions, relatively longer and narrower chip breaking points proximate the acute cutting corners, and relatively shorter and wider chip breaking points proximate the obtuse cutting corners. A chip breaking ramp surface flanks each of the relatively longer and narrower chip breaking points and each of the relatively shorter and wider chip breaking points. The chip breaking ramp surfaces form a series of non-collinear lines that are at a non-zero angle with respect to the cutting edge.
