A plurality of throw-away tips are installed along the circumferential direction on the outer periphery of the tip of the end mill body, spaced apart from the axis of the end mill body, and the inner circumferential side of the throw-away tips is mounted in the center of the tip of the end mill body. The throw-away tip is formed by forming an exposed core storage recess, and the cutting edge on the tip side of the end mill body and extending from the outer circumferential side to the inner circumferential side is the bottom edge, and the outer circumferential end of the bottom edge A throw-away type end mill characterized in that cutting edge ridges extending from the inner circumferential end toward the base end in the axial direction of the end mill body are an outer circumferential cutter and an inner circumferential cutter, respectively.
