PROBLEM TO BE SOLVED: To easily and safely perform the attaching/removing of a cutter, and eliminate the accumulation of cutting chips and the generation of noises. SOLUTION: In a groove 3 of a holder 1, a slider 8, a cutter pressing/fixing body 25, and a cutter 33 are provided. By sliding the slider 8 by an operation of the holder 1 in the axial direction, and moving the cutter pressing/fixing body 25, the cutter 33 can be attached/detached to/from the holder 1. As a result, the cutter 33 can be attached/detached without removing the holder 1 from a cutting machine by a single operation, and the above mentioned operation is performed on the end surface of the holder 1, and there is no fear that hand, etc., touch the cutter 33, and the attaching/detaching of the cutter 33 can be easily and safely performed. Also, there is no hole on the side surface of the holder 1. As a result, cutting chips do not accumulate in a hole, and there is no fear that a wind passing noise due to a hole generates. |
