Abstract: PURPOSE: An end mill having 2 shift twist angle for a thin plate manufacture is provided to minimize the twist angle of the end-blade which shreds thin plate and maximize the twist angle of the middle-blade except for the end-blade to reduce the vibration of the side wall processing. CONSTITUTION: The end mill having 2 shift twist angle for the thin plate manufacture includes a plurality of shredding blades. A plurality of shredding blades is formed along the outer circumference. The shredding blade(1) continuously form the end-blade(1a) of the end part of the end mill and the middle-blade(1b) except for the end-blade. The end angle(Ae) of the end-blade is formed smaller than the middle angle(Am) of the middle-blade.
