にしたことを特徴とするクランプバイト。[Claims for Utility Model Registration] One end of the rod-shaped holder 1 is provided with a chip seat 3 having an upper jaw portion 2 and a mounting hole 5 spaced apart behind the chip seat 3. A mounting screw 6 is disposed in the mounting screw 6, and when the mounting screw 6 is screwed in, the upper jaw portion 2 is elastically deformed, and the cutting blade tip 4 inserted into the tip seat 3 is pressed and fixed. In the clamp bit, the mounting screw 6 includes a tapered head 6a and a threaded portion 6b, and the mounting hole 5 includes a tapered hole 5a and a threaded hole 5b to fit the mounting screw 6. At the same time, the tapered hole 5a is divided into two by forming a slit 7 in a direction perpendicular to the protruding direction of the upper jaw portion 2, and a wedge formed by the tapered head 6a of the mounting screw 6 on the upper jaw portion 2 side. A pressure receiving surface 8 is configured, and when the mounting screw 6 is screwed into the mounting hole 5, the upper jaw portion 2 is configured such that when the mounting screw 6 is screwed into the mounting hole 5, the pressure receiving surface 8 of the tapered hole 5a receives the pressure from the tapered head 6a. This clamp bit is characterized in that it tilts toward the tip seat 3 side when pressure is applied, and its pressing lower surface 10 presses and fixes the cutting blade tip 4.
