Abstract: The present invention relates to a coated cutting tool comprising a cemented carbide substrate comprising WC, a metallic binder phase and gamma phase, where the cemented carbide has a well distributed gamma phase and where the cemented carbide have a reduced amount of abnormal WC grains. Further, the coated cutting tool is provided with a CVD coating comprising a TiCN and an α-Al 2 O 3 layer where said α-Al 2 O 3 layer exhibits a texture coefficient TC(0 0 12)≥7.2 and where in the ratio I(0 0 12)/I(0 1 14)≥1. The coated cutting tool according to the invention has an increased resistance against plastic deformation while maintaining the toughness.

Abstract: The present invention relates to a cutting tool comprising a cemented carbide substrate comprising WC, a metallic binder phase and gamma phase, where the cemented carbide has a well distributed gamma phase and where the cemented carbide have a reduced amount of abnormal WC grains. The cutting tool according to the invention has a more predicted tool life and an increased resistance against plastic deformation.
