摘要： In the radius end mill, main gash faces has an angle of inclination with respect to an axis that is smaller than a twist angle of chip discharge flutes. The main gash faces are formed on inner circumferential sides of distal end portions of wall surfaces that face in a tool rotation direction of helically twisted chip discharge flutes, which is formed on an outer circumference of a distal end portion of a tool body that is rotated around the axis. End cutting edges are formed on a distal end of the main gash faces. Sub gash faces has an angle of inclination with respect to the axis that is greater than that of the main gash faces. The sub gash faces are formed on an outer circumferential side of the main gash faces such that they extend away via step portions from the main gash faces. In addition, corner cutting edges that have a protruding arc-shaped contour are formed to be continuous with an outer circumferential side of the end cutting edges extending from a distal end as far as an outer circumference of the sub gash faces.

摘要： In this insert, in addition to the insert being formed so that the cutting edge is twisted at a helix angle within the range of 5° to 25° about the axis when the insert is attached to the insert mounting seat, the thickness of the insert body at the flank located on a straight line, which passes through the center of the rough hemisphere formed by the rotational locus of the cutting edge and forms an angle of inclination of 90° relative to the axis, is set to be within the range of 0.5D to 0.9D relative to the thickness D of the rough plate that composes the insert body. As a result, since a comparatively gentle but adequately large helix angle is imparted to the cutting edge, cutting resistance decreases. In addition, since the thickness of the insert body at the flank on the rear end side of the insert body is not excessively thin, the rigidity of the insert body is adequately secured.
