Claims

[Scope of utility model registration request]

A cutting tool with approximately the same diameter as the shank is fastened axially to the tip of the shank connected to the main shaft of a machine tool such as a boring machine with a bolt, with the cutting edge protruding in the radial direction of the shank. A detent key parallel to the protruding direction of the cutting edge and orthogonal to the axial direction of the shank and a key groove that fits into the key are provided on both joint surfaces of the cutting tool and the bolt is inserted into the tool. A boring tool in which the hole is an elongated hole parallel to the key and the keyway.
