PROBLEM TO BE SOLVED: To provide a heat resisting hard coating covered tool provided with a hard coating having further excellent heat resistance and oxidation resistance and with excellent wear resistance in high hardness. SOLUTION: This heat resisting hard coating covered tool 10 is provided with a base material 12 made of, for instance, cemented carbide alloy (equivalent product to JISZ10 mainly composed of WC-10Co) and a heat resisting hard coating 14 secured onto a surface of this base material 12. By constituting the material of this heat resisting hard coating 14 from (TixAl1-x-y (SiC)y)N (however, 0.3<=x<=0.7, 0.02<=y<=0.2), the material is excellent in heat resistance, oxidation resistance and wear resistance provided with high hardness, so as to obtain the heat resisting hard coating covered tool 10 excellent in heat resistance, oxidation resistance and wear resistance in high hardness even in high temperature cutting such as dry cutting.
