に設けられていることを特徴とするエンドミル。[Claim for Utility Model Registration] A disc-shaped throw-away chip is placed on a chip mounting seat of a base metal formed at the tip of a cylindrical tool body, and this throw-away chip is formed in the center of the tool body. In the end mill fixed to the tip mounting seat with a screw through a mounting hole, the throwaway tip has a rake face formed in a convex shape as it goes toward the mounting hole, and the throwaway tip The tip of the cutting edge of the chip is eccentric by a predetermined dimension from the rotational axis of the tool body when viewed from the tip, and the cutting edge on the rotational axis side from the tip of the cutting edge passes near the rotational axis. What is claimed is: 1. An end mill characterized in that the end mill is provided in such a manner that at least the cutting blades outside the tip of the cutting blade are located in the counter-rotation direction as they go in a radial direction from the rotation axis.
