Claims

[Scope of utility model registration request]

There are two or more cutting chips at the tip of the tool body.
A throw-away type in which the inner edges of the cutting blades are spaced apart from each other and are removably fixed by a fixing screw that passes through a through hole provided in the cutting blade tip and is screwed into the tool body. In the drill, the cutting tip is provided in the tool body so as to be movable in the axial direction of the tool body, the through hole is formed in the shape of a long hole long in the axial direction of the tool body, and the cutting tip is provided in the tool body. A throw-away drill, characterized in that a position adjustment member is provided that comes into contact with a rearward facing surface and changes the position of the cutting tip in the axial direction of the tool body.
