う付は式のエンドミル。[Claims for Utility Model Registration] At least two torsion tips 3 are brazed to the outer circumferential portion of the rod-shaped tool body 1 along chip pockets 4, and these torsion tips 3 have a front cutting edge. Brazing is performed using a type end mill so that the ridge 5 and the peripheral cutting edge 6 are shaped respectively, and the torsion tip 3 has a torsion angle A of 25° to 25° in the axial direction.
45°, the rake angle B in the radial direction is selected from the range of 3° to 1°, and the rake face on the side of the front cutting edge 5 has a part that is smaller than the torsion angle A and has a twisting degree. By grinding, a chamfered portion 7 having a land width C of 0.1 to 0.3 mm (71 land width C) is formed, and a chamfered portion 7 having a land width C of 0°:01 to 0.057 is formed on the front cutting edge 5 and the outer cutting edge 6. This is a brazing type end mill that is characterized by a honing process.
