A tip part is provided on the outer periphery of the tip of the milling cutter body that rotates around the axis, with its main cutting edge located on the tip side of the milling cutter body and forward in the rotational direction, and with a positive axial rake angle. An outer peripheral tip portion is provided on the outer periphery with its main cutting edge located on the outer peripheral side of the milling cutter body and forward in the rotational direction and with a negative axial rake angle, and the tip portion and the outer peripheral tip portion are A main cutting edge is formed on the ridge of the plane as a polygon in plan view, and a rake face continuous to this main cutting edge is formed outside the line connecting the tip of the cutting edge and the rear end of the cutting edge at the center of the main cutting edge. It is formed by a convex curved surface protruding in the direction, and further, the diameter of the main cutting edge of the distal tip portion in the rotation trajectory is 0.1 mm to 3 mm larger than the diameter of the main cutting edge of the outer peripheral tip portion in the rotation trajectory.
.. Vertical milling cutter characterized by setting 0mm larger.
