工具。[Claims for Utility Model Registration] The center of rotation of the tool body 2a is provided with a cutting edge tip 3 made of a polycrystalline sintered body such as diamond or cubic boron nitride. In a cutting tool in which the outer peripheral edge portion of the flute groove 4 is provided with an outer peripheral cutting edge tip 5 also made of a polycrystalline sintered body, the leading edge tip 3 is one of the leading edge cutting edges constituting the tip angle α. The ridge 6a extends so as to be continuous with the outer circumferential cutting edge ridge 7a having a helix angle of 0° formed on the outer periphery, and the other tip cutting edge ridge 6b extends so as to be interrupted without forming the outer circumferential cutting edge ridge 7a. A large number of the outer circumferential tips 5 are arranged in series along the flute groove 4 so as to form a twist angle θ, and the outer circumferential cutting tips 5 are arranged in succession in the flute groove 4 provided with the tip edge tip 3. is its outer cutting edge ridge 7b
The peripheral cutting edge 5, which is formed so as to be continuous with the outer peripheral cutting edge 7a of the leading edge tip 3, and which is connected to the flute groove 4 not provided with the leading edge tip 3, is the most advanced peripheral cutting edge tip. 5 is formed from the axial position where the outer cutting edge ridge 7a of the leading edge tip 3 starts on the rotation locus, so that a step amount δ is formed between the peripheral cutting edge ridge 7b and the leading edge tip 3. A cutting tool characterized in that it is designed to be
