削用カツター。[Claims for Utility Model Registration] A suitable number of blades 2 each having a digging tip 16 are disposed on the outer periphery of the annular end of the cutter body 1, which is approximately tube-shaped, and is secured by a mounting screw 3 and a nut 4. In a fixed excavation cutter, the cutter main body 1 has a receiving recess 5 formed on the outer circumferential surface of the annular end thereof, and a mounting hole 7 formed in the recessed surface 6 of the receiving recess 5. The blade 2 is provided with an engagement step 8 that fits into the receiving recess 5 on the mounting end side, and a tapered hole 9 that widens toward the outer circumference with respect to the mounting hole 7. The mounting screw 3 is located in the tapered hole 9 by being connected to a threaded portion 14 located on the mounting hole 7 side and expanding from this threaded portion 14, so that the mounting screw 3 is located in the tapered hole 9 and holds the blade 2. The nut 4 consists of a tapered head 15 that presses the cutter body 1 axially rearward, and the nut 4 has a threaded portion 14 of the mounting screw 3.
An excavation cutter characterized by being adapted to be screwed into.
