Zusammenfassung:	To provide a coated cutting tool having excellent abrasion resistance and defect resistance, whose tool life can be elongated more than before.SOLUTION: A coated cutting tool 6 includes a base material 1 and a coated layer 5 formed on the base material 1. The coated layer 5 includes a complex compound layer 3. The complex compound layer 3 has a composition represented by a formula:(Ti1-x-yAlxWy)N. An average thickness of the complex compound layer 3 is 1.0 μm or more and 6.0 μm or less. In the complex compound layer 3, a value of an orientation index TC (422) of a cubic crystal (422) surface represented by the following formula (2) is 2.0 or more and 5.0 or less.SELECTED DRAWING: Figure 1 【課題】耐摩耗性及び耐欠損性に優れ、従来よりも工具寿命を長くすることのできる被覆切削工具を提供する。【解決手段】被覆切削工具６は、基材１と、基材１の上に形成された被覆層５とを含む。被覆層５は、複合化合物層３を含む。複合化合物層３は、（Ｔｉ１−ｘ−ｙＡｌｘＷｙ）Ｎで表される組成を有する。複合化合物層３の平均厚さが、１．０μｍ以上６．０μｍ以下である。複合化合物層３において、下記式（２）で表される立方晶（４２２）面の配向性指数ＴＣ（４２２）の値が、２．０以上５．０以下である。【選択図】図１
