Milling steel. The machinability of steel differs depending on alloying elements, heat treatment and manufacturing process (forged, cast, etc.). In soft, low-carbon steels, built-up edge and burr formation on the workpiece are the main issues. In harder steels, the positioning of the cutter becomes more important for avoiding edge chipping.
Milling inserts and grades for hardened steelGC1010 is a PVD-coated grade for light roughing to finishing operations. With its exceptional resistance to plastic deformation, thermal cracking, and other types of wear, this grade can withstand long periods of time in cut and is suitable for machining hardened steel from 36 HRC and higher.
