A multiple faced cutter insert usable with lathes and turning machines, shapers, planers or milling cutters having a plurality of cutting edges associated with chip forming recesses. The adjacent cutting edges and lateral faces intersect at corners free of a radius and the chip forming recess associated with each cutting edge adjacent a corner produces chip flow at the corner substantially perpendicular to the associated cutting edge and recess. Preferably, the insert is of a regular pentagonal or hexagonal configuration to provide extensive support of each insert cutter corner to minimize corner breakage.
