Abstract

A coated cutting tool of a cemented carbide substrate made of WC, a metallic binder phase and a gamma phase has a well distributed gamma phase and a reduced amount of abnormal WC grains. Further, the coated cutting tool is provided with a CVD coating of TiCN and an α-Al2O3 layer, wherein the α-Al2O3 layer exhibits a texture coefficient TC(0 0 12)≥7.2 and wherein in the ratio I(0 0 12)/I(0 1 14)≥1. The coated cutting tool has an increased resistance against plastic deformation. whilst maintaining toughness.
