Provided are: a hard film for tools, having high hardness, low friction properties, deposition resistance, and oxidation resistance; and a metal machining tool. The hard film (30) for tools comprises X1-a-bZaOb (X indicates at least one type of metal element selected from Mo, V, and W, and Z indicates at least one type of non-metal element selected from N and C) or (X1-cYc)1-a-bZaOb (X indicates at least one type of metal element selected from Mo, V, and W, X indicates at least one type of metal element selected from Ti and Cr, and Z indicates at least one type of non-metal element selected form N and C.) A hard film for tools that has high hardness, excellent low friction properties, excellent deposition resistance, and excellent oxidation resistance can be obtained by introducing oxygen. |
