Coated tool

Abstract

A coated tool in a non-limiting embodiment of the present disclosure includes a base and a coating film located on the base. The coated tool includes a first surface, a second surface adjacent to the first surface, and a cutting edge located on at least a part of a ridge part of the first surface and the second surface. The coating film includes an AlTiN film. The coating film has a first compressive stress σ11 in a first direction which is parallel to a surface of the base and intersects with the cutting edge at an angle of 90°, and a second compressive stress σ22 in a second direction which intersects with the first direction at an angle of 90°. The first compressive stress σ11 is different from the second compressive stress σ22.
