Attachment apparatus attaches the housing to the end of a pipe so that the central axis of the machine and pipe are substantially coaxial. Attached to the shaft is a cutting tool assembly which rotates with the shaft to cut the end of the pipe. Linear and radial feed components provide, respectively, generally longitudinal and transverse motion to the cutting tool assembly relative to the central axis of the machine.
