ABSTRACT:
A cutter insert is provided which is adapted to be supported on a flat platform on a cutter body and abutting edgewise against walls upstanding from said platform. The insert comprises a flat block of cutting material in the geometric shape of a parallelogram having a hole extending therethrough between the upper surface and the mounting surface of the block to receive a screw for securing the block to the platform. The upper surface of the block terminates at opposite ends in radii. The cutter insert further includes a rake face and a clearance face on opposite sides of the hole with said upper surface and said faces constituting cutting edges defined by the intersections of said faces and said upper surface, and an angular facet at diagonally opposed ends of said radii so as to form a chip splitter at the juncture of the cutting edge of the rake face and the cutting edge of the angular facet.
