ABSTRACT:
A device for removing pipe attached to a fitting includes cutting apparatus for removing the pipe disposed within the fitting. A wrench apparatus is connected to the cutting apparatus for gripping the fitting to prevent its movement when the cutting apparatus is activated. Alternatively, this device may be used as a reaming device which permits radial movement of the cutting blades into engagement with a pipe after the cutting blades have been inserted within the pipe.
