1. A tool operable to expand an end of a pipe, the tool comprising: a plurality of jaws movable between a closed position and an expanded position and rotatable about a longitudinal axis; a rotation collar rotationally coupled to each of the plurality of jaws; a shuttle, selectively engageable with the rotation collar and rotatable between a first orientation and a second orientation; and a spindle movable between a first position in which the shuttle is in the first orientation and is disengaged from the rotation collar, a second position in which the shuttle is in the first orientation and is engaged with the rotation collar, and a third position in which the shuttle and the rotation collar are rotated together to the second orientation, the rotation of the rotation collar producing a corresponding rotation of the plurality of jaws while the plurality of jaws is in the closed position, wherein movement of the spindle to a fourth position moves the plurality of jaws to the expanded position and maintains the engagement of the shuttle and the rotation collar in the second orientation.
