Claims

[Scope of utility model registration request]

In an end mill in which a plurality of cutting blades are provided on the outer periphery of an end mill body that rotates around an axis and are inclined toward the rotational direction with respect to the axis, some of the cutting blades are arranged so that the axial rake angle of the cutting blades is An end mill characterized by having an axial rake angle arranged differently from the one shown in FIG.
