Abstract
Provided is a coated tool exhibiting enhanced wear resistance and adhesiveness of an aluminum oxide layer and superior wear resistance and defect resistance. A cutting tool () in which at least a titanium carbonitride layer () and an aluminum oxide layer () having an α-type crystalline structure are laminated in that order on a surface of a substrate (). A surface-side Tc(116) in a surface-side peak is greater than a substrate-side Tc(116) in a substrate-side peak where Tc(116) is an orientation factor of the aluminum oxide layer () when comparing the substrate-side peak detected by measuring a portion on a substrate () side of the aluminum oxide layer () and the surface-side peak detected by measuring a portion on a surface side of the aluminum oxide layer () in X-ray diffraction analysis of the aluminum oxide layer ().
