A cutting tool made of a cemented carbide substrate of WC, a metallic binder phase and gamma phase is provided. The cemented carbide has a well distributed gamma phase and a reduced amount of abnormal WC grains. The cutting tool has a more predicted tool life and an increased resistance against plastic deformation.

Cutting tool

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 &#x3b1;-AlOlayer, wherein the &#x3b1;-AlOlayer exhibits a texture coefficient TC(0 0 12)&#x2265;7.2 and wherein in the ratio I(0 0 12)/I(0 1 14)&#x2265;1. The coated cutting tool has an increased resistance against plastic deformation. whilst maintaining toughness.
