Abstract: The cutting inserts (52) are provided with positive cutting geometry and are especially adapted for service in face milling and shoulder milling raw castings and other hard-shelled workpieces (45) by providing a cutting edge land (64) which varies in width along the cut from narrowest at the bottom of the main cutting edge (60) to broadest where the cutting edge (60) meets the hard surface of the workpiece (45). In double-ended cutting edges, i.e., where the cutting edge is designed to cut equally in cutters of either hand of rotation, the maximum land width is at the cutting edge midpoint and tapers to minimum width at each end.
