Claims

[Claims for Utility Model Registration] (1) It has a generally cylindrical shape and is fitted into the through hole of the bushing plate with a radial gap and attached to the bushing plate, so that the rotary cutting tool rotates. In a guide bush for a rotary cutting tool, the guide bush allows the rotary cutting tool to penetrate through the bushing plate, and at least a part of the inner circumferential surface serves as a guide surface that prevents the rotary cutting tool from moving in the radial direction. It includes two members: an outer cylinder that fits into the hole, and an inner cylinder having the guide surface, and the inner cylinder and the outer cylinder can be fitted with substantially no gap, and the inner cylinder The inner cylinder and the outer cylinder are fixed with the shoulder surface facing outward in the radial direction in close contact with the outer cylinder, and the inner cylinder is allowed to be removed from the outer cylinder while the outer cylinder remains fixed to the bushing plate. A guide bushing characterized by being provided with a fixing device. (2) At least a portion of the inner circumferential surface of the outer cylinder and the outer circumferential surface of the inner cylinder are tapered surfaces that tightly fit into each other when the shoulder surface is in close contact with the outer cylinder. A guide bush according to claim 1.
