Claims

[Scope of utility model registration request]

The drilling angle is determined by a cylindrical guide that guides a drill bit, a plate that rotatably supports the guide, and a base that supports the plate so that it can slide in the width direction of the workpiece and serves as a reference surface during machining. A drill bit guide that can be freely changed, characterized in that it has a drill hole positioning pointer that rotates together with the cylindrical guide and is movable in the guide direction of the drill bit. .
