ことを特徴とするエンドミル。 In an end mill that has a pair of cutting edges at the tip of the tool body, the main cutting edge is formed near the center of the shaft, and the cutting edge that cuts the center of the shaft is a convex cutting edge, and the bottom cutting edge is linear. In addition to cutting mainly on the front side, the auxiliary cutting blade is placed from the outer periphery to a position in front of the axis center point so that the outer peripheral cutting edge is mainly involved in cutting, and the pair of cutting blades are placed at the center of the tool axis. The radial angle connecting the end of the cutting edge is 5.
~20 degrees so that the bottom cutting edge is placed on the rotational front side of the tool, and the axial positional relationship between the end surfaces of the bottom cutting edge of the main cutting blade and the auxiliary cutting blade is set so that the bottom cutting edge is closer to the auxiliary cutting edge than the main cutting blade. An end mill characterized in that an end mill is formed on the inside by 0.01 to 0.6 mm.
