摘要:
A wood or resin cutting tool with improved durability is provided. The wood or resin cutting tool is composed of a base material made of steel or a cemented carbide alloy, and a coating formed on at least one of the rake face and the clearance face of the cutting tool. The coating includes a periodic structure layer made of chromium oxynitride, in which high oxygen regions having a high concentration of oxygen in the texture and low oxygen regions having a lower concentration of oxygen in the texture than the high oxygen regions periodically exist in the thickness direction of the coating. The periodic structure layer is formed such that the nitrogen concentration periodically turns high and low in the thickness direction of the layer corresponding to the high oxygen regions and the low oxygen regions.
