Zusammenfassung:PROBLEM TO BE SOLVED: To accurately bore by suppressing the runout of a tool body without using a guide pad to prevent chattering.SOLUTION: Cutting edges 9A are provided so as to project from the distal end outer periphery of a tool body 1 which is rotated about an axis O and formed in a columnar shape having the center at the axis O. Pressing members 16 each having a spherical convex portion on the outer peripheral side of the tool body 1 are attached to mounting recesses 15, each of which is formed on the opposite side of the cutting edge 9A with the axis O interposed therebetween at the distal end of the tool body 1, further to the rear end side than the cutting edge 9A in the direction of the axis O, while being pressed to the outer peripheral side of the tool body 1.
