Abstract: A mobile device for simultaneously cutting, chamfering and grooving a pipe. The device having a frame, at least one pipe collet-clamp attached to the frame and defining a principal axis, a split carriage rotatably mounted with respect to the frame about the axis and adjacent to the clamp(s), a router affixed to the split carriage and having a cutting-chamfering bit, a grooving router and a drive motor for rotating the carriage. The routers orbit around the pipe and simultaneously cuts the pipe into two chamfered pipes with grooves. A method is also provided for cutting through a pipe, chamfering the cut ends thereof and grooving the pipe.

Abstract: 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.
