Designed for rapid metal removal when machining cast and ductile iron, the PWC 15 degree semi shoulder cutter features tangentially mounted inserts to maximise the amount of teeth in contact with the workpiece. Cutters range from 80 200mm diameter in standard or fine pitch and utilise newly developed coated insert grades ACK200 / ACK300 at speeds between 200 -300m/min for cast iron and ACK100 / ACK200 at speeds between 150 250m/min for ductile cast iron. Specify G for general purpose application and H for heavy interrupted cuts or unstable machining conditions.
