Abstract
A coated cutting tool has a CVD coated and a substrate of a cemented carbide, wherein the metallic binder in the cemented carbide includes Ni. The CVD coating has an inner layer of TiN and a subsequent layer of TiCN. The C-activity relative to graphite in the metallic binder is lower than 0.15 and an average d electron value of the metallic binder is 7.00-7.43, wherein an interface between the substrate and the inner TiN layer is free of Ti-containing intermetallic phase.
