Abstract

A coated tool of the present disclosure may include a base and a coating layer covering at least a part of the base. The base may include a hard phase of a carbonitride including Ti and a binder phase including at least one of Co and Ni and has a thermal expansion coefficient at 25 to 1000° C. of 9.0×10/° C. or more. The coating layer may include a TiCN layer and an AlOlayer positioned on the TiCN layer. The TiCN layer may have a compressive stress of 250 to 500 MPa. The AlOlayer may have a thickness of 2 μm or more and a compressive stress of 450 MPa or more, and the value of the compressive stress is greater than the compressive stress of the TiCN layer.
