Abstract
A tool operable to expand an end of a pipe, such as PEX pipe, has a jaw assembly with jaws movable between a closed position and an expanded position and rotatable about a longitudinal axis. A motor drives an output spindle driven by the motor, which in turn drives a radial cam. A wedge is movable by the radial cam in a reciprocating motion along the axis, causing the wedge to move between a first position where the jaws are in the closed position and a second position where the jaws are in the expanded position. A rotating ring is mounted on the wedge and connected to the jaws. The rotating ring is driven by the output spindle for rotating the jaws about the axis.
