A method and tool are disclosed for removing a plastic water closet flange from the waste pipe to which it is attached so that a new flange may be chemically bonded to the existing waste pipe. A preferred embodiment of the water closet flange removal tool includes an axial shaft, a cylindrical guide body attached to a lower end of the shaft, the guide body having an outer diameter slightly less than the inner diameter of the waste pipe so that it is slidably insertable therein, and a cylindrical-walled cutter, having an inside diameter slightly greater than the outer diameter of the waste pipe, mounted above the guide body. For a preferred embodiment of the tool, both the guide body and the cylindrical-walled cutter are coaxially mounted on the shaft. The cylindrical-walled cutter is open at the lower end thereof so that it can slide over the waste pipe as the flange is cut therefrom. In order to use the tool, an upper end of the shaft is coupled to a drill motor, the guide body is inserted through the central opening of the flange and into the waste pipe. The shaft is then rotated with the drill motor. With the cutter rotating, the tool is driven further into the waste pipe until the flange is cut therefrom. The tool is then retracted and the flange discarded.
