るエンドミル。 A bottom blade is formed at the tip of the tool body and is spaced apart from the axis of the tool body and extends from the inner circumferential side to the outer circumferential side, and an inner circumferential cutter is formed that extends rearward from the inner circumferential end of the bottom blade. In an end mill in which an outer circumferential cutter is formed rearward from an outer circumferential end of a bottom cutter, and a core storage recess is formed in a central portion of the tip surface of the tool body that includes the axis, the tool main body has a core storage recess. An end mill characterized in that a hole extending rearward from the rear part is provided, and a shaft member having toughness greater than the material of the tool body is fitted into the hole.
