A CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 10-300 MPa and an α-Al 2 O 3 -layer with a high surface smoothness of <0.1 μm as measured by AFM-technique is disclosed. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry of F80 grits of Al 2 O 3 followed by a second wet blasting treatment with a slurry of F320 grits of Al 2 O 3 . |
