摘要：
A rotary cutting tool is provided which is less likely to cause chips to get stuck, and which can be manufactured at a low cost.The rotary cutting tool includes a body having a relief surface (6) and a rake face (7) which is connected to the relief surface (6). An oxide film (9) is formed on the rake face (7) by oxidizing the surface of the body, and a hard film (8) is formed on the relief surface (6) and the oxide film (9). The hard film (8) is made of a metal carbide, a metal nitride, a metal carbonitride, or a solid solution thereof.
