Abstract

PURPOSE:To prevent looseness of a head, by closely attaching the head to a holder through contact fit to protrusive parts in a fitting hole of the holder, that is, by removably mounting the head, provided with a cutting edge, to the holder simultaneously forming alternately hollowed and protrusive parts circumferentially peripherally of the head. CONSTITUTION:A head 1 and holder 2 are separately formed, and the head 1 is removably mounted to the holder 2. A large contoured shaft part 4 and small contoured shaft part 5 are provided in two stages to a rear end side of the head 1. Protrusive parts 8, 8 are formed in the peripheral surface while hollowed parts 9, 9 in the rest of the surface in its axially symmetrical position throughout an angular range of slightly smaller than 90 deg. in the large contoured shaft part 4. Further protrusive parts 10 and hollowed parts 11 are formed, respectively in equal width correspondingly to said protrusive parts 8 and hollowed parts 9, in a large contoured hole 6 of the holder 2, and the protrusive parts 8 of the head 1 and the protrusive parts 10 of the holder 2 are mutually closely contacted and fixed at the time of fitting.
