TurningMillingDrillingTechnicalInformationIndex Solid carbide milling Grade overview Coated cemented carbide PVD A Grade Grade description KMD401 PVD coated carbide substrate for high performance milling application of non-ferrous metals, CFRP and GFRP and organicmaterials. The DLC layer has very good wear protection and high thermal stability. B KMG303 PVD coated carbide substrate for universal milling application of steel (up to HRC<=48), stainless steel and cast iron. KMG405 PVD coated carbide substrate for high performance milling application of steel (up to HRC <55), stainless steel, super alloymaterial and cast iron. High wear resistance and toughness for a wide application field. C KMG555 PVD coated carbide substrate for hard milling application of steel (HRC 55–68), highest wear resistance and toughness for bestcutting result. KMG309 PVD coated carbide substrate for non ferrous materials. High wear resistance even in abrasive materials. D Uncoated cemented carbide Grade Grade description YK30F Uncoated K30 carbide substrate for steel, stainless steel, cast iron and non ferrous materials. E YK40F Uncoated K20–K30/N20–N30 carbide substrate for cast iron and non ferrous materials. B 266
