Claims

[Scope of utility model registration request]

An adapter that is attached to the tip of the main shaft of a machine tool and has a protrusion on the tip surface, and a cutter body that is attached to the tip of the adapter by fitting the protrusion of the adapter into a tapered hole formed on the rear end surface. Then, a distal end portion protruding from the adapter, which is provided in the adapter so as to be movable in the axial direction thereof, is removably engaged with the engaging portion of the cutter main body, and is moved rearward in the axial direction of the adapter. A cutter fastening device comprising a clamper rod for attaching a cutter body to an adapter, wherein a tapered portion of the adapter is formed in the protruding portion of the adapter, the diameter of which decreases toward the distal end; 1. A cutter fastening device characterized by forming a tapered hole portion corresponding to the above.
