Claims

[Claims for Utility Model Registration] The base of a cylindrical member with a conical tip is formed into a shank, and from the side of the shank to the tip, a gently curved curve when viewed from the side, followed by a (horizontal straight line) and cut a chip discharge path with a shallow central portion of the horizontal plane, and open a part of the tip of the cylindrical member spirally in the direction of its rotational force and fan-shaped when viewed from the tip. A drill body is configured by communicating with the chip discharge path and forming a counter-rotation edge of the fan-shaped opening into a drilling blade, and a liquid injection hole is drilled through the drill body from the base end to the tip end. A woodworking drill with a liquid injection hole.
