Abstract
A virtual plane obtained by a locus when a tangent line, which passes through a tool distal end edge, of a virtual circle formed when a tool distal end edge of a cutting edge is rotated in a tool circumferential direction is moved parallel to a tool axial line is a reference plane, an angle (ARt) at which a cross line of the reference plane and the cutting edge virtual plane, is inclined with respect to the tool axial line projected onto the reference plane, is in a range of −30 degrees to −60 degrees, an angle (RR) at which a cutting edge tangent line which passes through the tool distal end edge and extends outward in a tool radial direction, is inclined with respect to a predetermined tool radial direction, which passes through the tool distal end edge, is in a range of −30 degrees to −75 degrees.
