Cutting fluid has been used for the cutting processing. However, the use of the cutting fluid contains the factor of the environmental problem. Therefore, the cutting fluid-less processing has been required. For one of the cutting fluid-less processing, the cold-air jet processing has been advocated. In the cold-air jet processing, it becomes important that the processing point is supplied, while temperature and pressure of the cold-air jet were kept. In this study, in order to efficiently supply the processing point with the cold-air jet, the endmill tool with air holes was produced experimentally, and the processing experiment was carried out. The following has been clarified : Effect of the air hole diameter of the tool on processing characteristics and effect of the tool hole direction on processing characteristics. From the experimental results, it is proven that there is no problem to 1.5mm at air hole diameter. And, it has became about 2.8 times the tool life than the dry-type processing in case of the endmill with the air holes which could supply the processing point whole area with cold-air jet.
