Abstract
A chipbreaking insert for metalcutting is useful for breaking chips over a wide range of speeds and feeds. In light cuts, the chips are broken by a finishing depression adjacent to the cutting corner. In deeper but still moderate cuts, the chips and broken by a chipbreaking groove which is parallel to the cutting edge. In heavy cuts, the chips are corrugated and deflected away from the workpiece by a series of cylindrical chip deflecting grooves spaced along the cutting edge.
