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 - M40S15-S25 medium application of stainless steel, super alloy and steel (milling). Good wearresistance and thermal stability in a wide application field. YB9320 P10 - P30M10 - M25 PVD multilayer coated M10–M25/P10–P30 carbide substrate for finishing to mediumapplication of stainless steel, super alloy and steel (grooving/milling). Optimized coatingstability for higher wear resistance and thermal stability in a wide application fi C YBG302 P15 - P30M25 - M40 PVD coated M25–M40/P15–P30 carbide substrate for medium roughing application ofstainless steel and steel (milling). Good wear resistance and toughness. 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.
