回転切削工具。 A tool body consisting of a shank part and a tip part having a cutting edge on the outer circumferential side of the other end, a supply hole extending inside the tool body, and an injection hole communicating with the supply hole and ejecting compressed air. A rotary cutting tool having:
The injection hole is composed of two types, a first injection hole and a second injection hole, and the first injection hole is compressed near the rotation locus on the rear end side of the cutting blade, or near the outer side of the rotation trajectory. The second injection hole is opened at a tip part closer to the shank than the rear end rotation locus position of the cutting blade or into a cutting discharge groove connected to the cutting blade at the tip part so as to blow out air. A rotary cutting tool characterized in that a chip evacuation groove at the tip portion is open to the cutting blade so that the chip ejects toward the cutting blade.
