Abstract

A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-AlOlayer containing a plurality of α-AlOcrystal grains. The α-AlOlayer includes a lower layer portion disposed at a side of the base material, an intermediate portion disposed on the lower layer portion, and an upper layer portion disposed on the intermediate portion. In a crystal orientation mapping performed on a polished cross-sectional surface of the α-AlOlayer using an EBSD, an area ratio of α-AlOcrystal grains with (001) orientation in the lower layer portion is less than 35%, an area ratio of α-AlOcrystal grains with (001) orientation in the intermediate portion is 35% or more, and an area ratio of α-AlOcrystal grains with (001) orientation in the upper layer portion is less than 35%.
