摘要： Provide is a coated cutting tool having excellent wear resistance and fracture resistance, and having longer life than that of the conventional products. The coated cutting tool of the present invention comprises a substrate and a coating layer formed onto the surface of the substrate. The coating layer contains an ± type aluminum oxide layer. A residual stress value at the (116) plane of the ± type aluminum oxide layer is greater than 0. A residual stress value at the (012) plane of the ± type aluminum oxide layer is smaller than 0.
