PROBLEM TO BE SOLVED: To provide a hard coating coated tool capable of simultaneously attaining significantly high oxidation resistance, wear resistance, lubricity, and adhesion for the accommodation of drying and high speed in cutting highly hard steel, and a complex hard coating coated tool capable of attaining further high adhesion by a combination with a conventional coating. SOLUTION: In this abrasive-resistant coating coated tool formed by coating a base surface with a hard coating, the coating is formed by applying coating of at least one layer A, which consists of chemical composition expressed by (Cra Si1-a )(Nx B1-x ), where 0.5<=a<1, 0.5<=x<=1 and which is composed of phases relatively rich in Si and poor in Si. In the layer A, an amolphous microcrystal (Cra Si1-a )(Nx B1-x ) is interposed. The abrasive-resistant coating coated tool is also constituted by alternately performing the coating of at least one layer of chemical composition generally expressed by (TiAl)N with each other.
