Abstract
A chamfer tool includes a main body, a driving shaft and a plurality of milling members. The main body, which rotates along an axis, has an inner surface and an outer surface located on opposite sides thereof; wherein the main body further has a plurality of mounting portions, each of which is connected to the inner surface and outer surface. The driving shaft is fixed to the main body to drive the main body to rotate. Each of the milling members has a first blade and a second blade, wherein the milling members are mounted on the mounting portions of the main body with the first blades protruding from the outer surface of the main body and the second blades protruding from the inner surface of the main body.
