ABSTRACT:
A pipe cutting or end prepping device capable of use in severely restricted spaces to cut through or shape for welding a hollow cylindrical pipe wall, which includes a rotatable tool bit support or carriage assembly adapted for insertion through an end of the pipe to be cut and located within the hollow bore of the pipe having one or more tool bits to cut into the pipe wall at the cutting site. A rotatable drive coupler is provided for releasably coupling a drive motor to the tool bit support or carriage for rotating the latter, and an anchor forming assembly in the form of a radially expandable and contractable annular collet forms a cylindrical pipe gripping surface to provide a stationary anchor station along the pipe adjacent the cutting site. A feed control assembly, for example, an elongated guide rod having a threaded end portion or a hollow tubular housing having a threaded end portion, together with a threaded drive nut coupled to the threaded end portion, supplies advancing force to the drive coupler and tool bit support or carriage for pulling the latter at a precisely controlled feed rate toward the anchor station to advance the tool bit or bits into the pipe wall at a predetermined rate.
