AbstractA pipe cutting system includes an annular pipe encircling band member with parallel edge surfaces for encircling the pipe to be cut, releasable structure for securing the band member in pipe encircling configuration, and structure for spacing the edge surfaces of the band from the outer surface of the pipe. A carriage assembly includes two pairs of opposed spaced guide members for engaging opposed edges of the band and providing stable guidance of the carriage assembly around the pipe and structure for fixedly mounting a cutting tool on the carriage assembly. The cutting tool assembly is secured to the carriage assembly for movement relative to the pipe, preferably about a pivot axis parallel to the axis of the pipe, and includes a drive motor, a manual motor control, and a cutter disc coupled to the drive motor and adapted to be driven in rotation by the drive motor in response to the manual motor control.
