PROBLEM TO BE SOLVED: To provide a film coating tool excellent in the anti-abrasiveness and equipped with a largely enhanced durability for machining. SOLUTION: The film coating tool is for a titanium-chromium compound film to be put on the surface of the tool base, wherein the film contains one or more of the carbide, nitride, carbonitride, carbonate, nitrate, and carbonitrate expressed by (Ti<SB>x</SB>Cr<SB>y</SB>Me<SB>z</SB>), where X, Y, Z show the mass proportion, provided that 0<X<0.999, 0<Y<0.40, 0≤Z<0.100, and that X+Y+Z=1, and further Me is metal elements belonging to Groups 4a, 5a, 6a in the Periodic Table excluding Ti and Cr. The film is located nearer the tool surface than an aluminum oxide film. COPYRIGHT: (C)2004,JPO
