ドミル。[Claims for Utility Model Registration] A cylindrical main body that can be rotated around its axis, and three or more chip discharge grooves formed along the longitudinal direction of the main body from the distal end surface of the main body. Hole drilling is performed using a throw-away tip for cutting the outer periphery of the hole and a throw-away tip for cutting the inner periphery of the hole, which are removably fixed to the tip of the main body. A drill-cum-end mill capable of performing deep groove machining with a side-cutting indexable tip that is fixedly fixed, wherein at least one side-cutting indexable tip is mounted on a groove surface in the direction of rotation in the groove, and the tip The surface of the groove faces in the direction of rotation, the cutting edge is located on one cylindrical surface, and the axial position of the chip on one groove surface is staggered with the chip on the other groove surface. The indexable indexable tip for cutting the inner circumference of the hole is attached to the distal end surface of the land forming a groove surface to which the distalmost tip of the indexable tip for cutting the side surface is fixed. It is fixed in a posture that is closer to perpendicular than parallel to the axis, while the one closest to the proximal end of the indexable tips for side cutting on the distal end side fixed to each groove surface is fixed. Place the indexable tip for cutting the outer circumferential portion of the hole on the groove surface, with the tip surface facing the rotation direction and all edges thereof positioned on the cylinder. An end mill that can also be used as a drill, and is fixed in the position in which it is placed.
