摘要： Provided is a coated tool in which a hard coating layer has excellent hardness and toughness and exhibits chipping resistance and defect resistance during long-term use. A surface-coated cutting tool is formed by coating the surface of a tool body with a (Ti 1-x Al x ) (C y N 1-y ) layer (the average amount Xavg of Al and the average amount Yavg of C satisfy 0.60 ‰¤ Xavg ‰¤ 0.95 and 0 ‰¤ Yavg ‰¤ 0.005).
