| PURPOSE: To prevent an edge part from cracking at the time of manufacture. CONSTITUTION: An end mill 1 is provided with a steel tool main unit 2 comprising a shank part 4 and a shaft part 5 extended from the shank part 4 and a hard alloy or high speed steel cylindrical edge part 3 externally fitted to be secured to the shaft part 5. A plurality of cutting edges 10 having a prescribed twist angle and a cutting chip discharge groove 11 partitioned between the cutting edges 10 are formed in a peripheral surface of the edge part 3. In the edge part 3, both end part internal peripheral surfaces are fixed by brazing to short scaled intermediate diametric parts 6a, 6b, and a clearance part 12 for avoiding connection of a peripheral surface of a small diametric part 7 to an internal peripheral surface of the edge part 3 due to difference of a thermal expansion amount between the edge part 3 and the shaft part 5 by heat, at the time of brazing, is formed between an intermediate part internal peripheral surface and a long scaled small diametric part 7 of the shaft part 5. The clearance part 12 is sealed with a filling agent 13 of lock tight or the like for preventing a chatter noise from being generated due to finely vibrating air in the clearance part 12.
