The present invention relates to a coated cutting tool comprising a substrate and a coating, wherein the coating comprises an inner α-AI 2 O 3 -multilayer and an outer α-AI 2 O 3 -single- layer. The thickness of the inner α-AI 2 O 3 -multilayer is 50% to 80%of the sum of the thickness of the inner α-AI 2 O 3 -multilayer and the thickness of the outer α-AI 2 O 3 -single- layer. The sum of the thickness of the inner α-AI 2 O 3 -multilayer and the outer α-AI 2 O 3 -single-layer is preferably 2-15 μm. Said α-AI 2 O 3 -multilayer consist of alternating sublayers of α-AI 2 O 3 and sublayers of TiCO, TiCNO, AITiCO or AITiCNO, said α-AI 2 O 3 -multilayer comprises at least 8 sublayers of α-AI 2 O 3 .
