Abstract
A cutting tool for metal material processing has a hard metal body and a multi-layer coating applied to the hard metal body in at least one surface area. The multi-layer coating includes the following, sequentially in direction from the hard metal body to the surface of the cutting tool: at least one layer TiCN, where x+y=1, x≧0, y>0; at least one layer TiCNO, where x+y+z=1, 0≦z≦0.03 and 0.5≦x≦0.85; at least one layer TiN, or TiCN, where 0.2≦x≦0.8 and x+y=1, or TiNB, where 0.0001≦v≦0.05 and y+v=1; at least one layer: TiNBO, where y+v+z=1 and 0.0001≦v≦0.05 and 0.01≦z≦0.6, or TiCNO, where x+y+z=1 and 0≦y≦0.5 and 0.01≦z≦0.6; and at least one outer layer κ-AlO. The at least one layer TiCNOhas a texture in the direction having a texture coefficient TC=1.3.
