A pipe cutting and forming tool particularly adapted for manual use in cutting and forming the ends of plastic pipe to receive seals and coupling structures for coupling plastic pipe to connectors or fittings and for sealing the pipe relative to such connectors or fittings; the tool comprising a frame carrying a pipe holder which engages the interior of a pipe and a pipe collar which engages the exterior of a pipe, both of which are mounted on the frame so as to allow rotation of the frame concentrically relative to the holder and the collar when fixed to the pipe; and a cutter and forming tool adjustably mounted on the frame to move radially inward and outward relative to an end of the pipe when held by the pipe holder and collar so that shoulders and seal engaging portions as well as grooves may be formed on the exterior of the pipe at the end for holding seals as well as locking means for sealing and locking a piece of pipe relative to a coupling or fitting.
