Abstract

The present invention relates to a CVD-coated cutting tool insert with a TiCxNy-layer with a low tensile stress level of from about 50 to about 390 MPa and an α-Al2O3-layer with a high surface smoothness with a mean Ra<0.12 μm as measured by AFM-technique. This is obtained by subjecting the coating to an intensive wet blasting operation.
