General turning Grade overview Coated cemented carbide PVD A Grade ISO Micro structure Grade description Turning P10 - P30 PVD coated M10–M25/P10–P30 carbide substrate for finishing to medium application of YBG202 M10 - M25 stainless steel and steel (milling). Good wear resistance in a wide application field. P10 - P30 PVD multilayer coated M20–M40/S15–S25/P10–P30 carbide substrate for finishing to B YBG205 M20 - M40 S15-S25 medium application of stainless steel, super alloy and steel (milling). Good wear resistance and thermal stability in a wide application field. Milling PVD multilayer coated M10–M25/P10–P30 carbide substrate for finishing to medium P10 - P30 YB9320 M10 - M25 application of stainless steel, super alloy and steel (grooving/milling). Optimized coating stability for higher wear resistance and thermal stability in a wide application fi C YBG302 P15 - P30 PVD coated M25–M40/P15–P30 carbide substrate for medium roughing application of M25 - M40 stainless steel and steel (milling). Good wear resistance and toughness. Drilling PVD coated N05–N20 carbide substrate for finishing to medium application in aluminum YBG101 N05 - N20 material. Coating only on the top face, in combination with the aluminum chip breaker, prevents build up edges and gives a smooth cut.
