Coated tool

A coated tool comprising,

• a base material comprising a first surface and a second surface;
• and
• coating layers located over the base material and comprising,
• a first layer including titanium carbonitride and located over the base material, and
• a second layer including aluminum oxide having an alpha-type crystal structure and located over the first layer;
• wherein
• the second layer comprises a first portion located over the first surface and a second portion located over the second surface, and
• a texture coefficient Tc1 (146) as measured on an outermost surface of the first portion is 1 or more, wherein the texture coefficient Tc (hkl) is a value expressed by the formula shown below on the basis of a peak of the second layer analyzed by an X-ray diffraction analysis:
• a texture coefficient Tc(hkl)={I(hkl)/I0(hkl)}/[(⅛)×Σ{I(HKL)/I0(HKL)}]
• wherein (HKL) represents a crystal face (012), (104), (110), (113), (024), (116), (214) or (146);
• each of I(HKL) and I(hkl) represents a peak intensity of a peak which is attributed to each crystal face and is detected by an X-ray diffraction analysis of the second layer;
• and
• each of I0(HKL) and I0(hkl) represents a reference diffraction intensity of each crystal face contained in a JCPDS card No. 00-010-0173.
