摘要： PROBLEM TO BE SOLVED: To prevent the degradation of finished surface accuracy and shortening of life of a tool by restraining cutting chips from acting to be pushed to a cutting material when cutting by a cutting edge 9 extended at a rear end side by exceeding a plane R in a ball end mill wherein the cutting edge 9 where a rotary locus around an axis O is a spherical shape is extended to exceed the plane R orthogonal to the O-axis passing through the center Q of spherical surface from a pointed head side in the axis-O direction toward the rear end side.
SOLUTION: The cutting edge 9 is formed to twist to a rear side in a rotation direction T of an end mill as it goes to a rear end side at a pointed head side section 9A in the axis-O direction rather than the plane R, and an angle of twist θ against the axis O is set up to gradually reduce toward the rear end side at a rear end side section 9B in the axis-O direction exceeding the plane R.
