ABSTRACT:
A router attachment for adapting a conventional screw gun for cutting sheets of drywall material includes a housing that is removably securable to the housing of the screw gun, an input shaft rotatably mounted in the housing for coupling with the screwdriver shaft of the screw gun, an output shaft rotatably mounted in the housing for coupling with a router bit and a step-up gear assembly for associating the input and output shafts so that rotation of the input shaft at a first rate of rotation drives rotation of the output shaft at a second, higher rate of rotation.
