A roller tool for forming an outwardly projecting ridge in a pipe, which tool is usable with the chuck or power head of a conventional pipe working machine, and a carriage suitable for mounting the roller tool and other tools on the pipe working machine. The roller tool has a female roller rotatably supported on a movable frame. The frame is fixed to the carriage, which in turn is pivotally mountable on the carriage supporting rails of the pipe working machine. One rail is fully encircled by a closed socket formed in the carriage, so that the roller tool cannot spontaneously disengage from the host pipe working machine. The other rail is partially encircled by an open socket formed in the carriage. The roller tool can pivot about the closed socket between an operational position and a standby position enabling the grooving machine to be utilized for grooving with the roller tool still attached. The roller tool has plural female rollers configured differently to provide ability to form the ridge at different distances from the end of the pipe being worked. In an alternative embodiment, conventional pipe working tools are used with the novel carriage.
