A bit for simultaneously cutting and chamfering a pipe is provided having a shaft defining an axis and having a shank portion at its proximal end and a working portion at its distal end. The working portion has a distal-most depth-cutting portion with at least one axially-offset leading cutting edge at the circumference of the shaft, a substantially axially-parallel lateral cutting edge extending from the distal end along the length of the depth-cutting portion and at least one chamfer-cutting portion between the depth-cutting portion and the shank portion.
