Abstract
A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-AlOlayer. The α-AlOlayer contains a plurality of α-AlOcrystal grains and a plurality of κ-AlOcrystal grains, and has a TC(006) of more than 5 in a texture coefficient TC(hkl). A ratio of Cto a sum of Cand C: [C/(C+C)×100](%) is 0.05 to 7%, where Cis a total number of peak counts of the α-AlOcrystal grains obtained from measurement data of x-ray diffraction for the coating, and Cis a total number of peak counts of the κ-AlOcrystal grains obtained from the measurement data of the x-ray diffraction for the coating.
