Abstract

A chamfering tool rotates about an axis. The chamfering tool comprises a rake face, a front flank face, a rear flank face, a front cutting edge and a rear cutting edge. The front flank face is contiguous to the rake face. The rear flank face is located axially rearward of the front flank face and contiguous to the rake face and the front flank face. The front cutting edge is defined by a ridgeline formed by the rake face and the front flank face. The rear cutting edge is defined by a ridgeline formed by the rake face and the rear flank face. In a radial direction of the chamfering tool, a front end of the front cutting edge is located inward of a rear end of the front cutting edge. In the radial direction of the chamfering tool, a front end of the rear cutting edge is located outward of a rear end of the rear cutting edge. The front cutting edge has a true rake angle larger than 0°. The rear cutting edge has a true rake angle larger than 0°.
