るスローアウェイ式の穿孔工具。- The tip for cutting near the center of rotation is removably fixed to a tip seat formed at a predetermined axial and radial angle at the end of the shank body of the drilling tool.
By forming a recess near the corner in a plane direction from the side surface, with the ridge line serving as the cutting edge, and positioning the recess at the center of the axis of the tool, it is possible to reduce the cutting edge (in both cases, the edge line on the outer circumference is used as the cutting edge of the tool). A throw-away type drilling tool characterized by being located on the forward side in the direction of rotation.
