PROBLEM TO BE SOLVED: To provide a tool covered with titanium carbonitroxide which can have an increased thickness and which can prevent the crystal grain size from becoming larger while can restrain protrusions from being locally formed, and having a cutting durability which are remarkably excellent in comparison with that of a conventional one. SOLUTION: This tool covered with titanium carbonitroxide has on its base body surface a single layer film of one kind, or a multilayer film of more than one kind among IVa, Va and IVa group metals such as carbide, nitride, carbon nitrate, carbon oxide, nitrogen oxide, carbon-nitrogen oxide and aluminum oxide. At least one of the layers is made of titanium carbonitroxide. In that tool, a maximum X-ray refraction peak value plane of a titanium carbonitroxide film is (422) surface. or (311) surface.
