ABSTRACT:
An adaptor is disclosed which is designed to be attached to an existing screwgun having a bit with a polygonally shaped end. The adaptor has a recess designed to drivingly receive the hexagonally shaped end of the bit and may be fixedly attached to the existing screwgun. The adaptor has gearing designed to allow rotation of a tool receiving adaptor at a much greater speed than the input speed. A saw blade may be attached to the tool receiving adaptor so that the inventive screwgun saw adaptor may be employed to convert a screwgun into a sawing device. In one embodiment of the present invention, an electrical circuit is incorporated into the adaptor which allows determination of the location of an electrical box behind a wall, which device includes a sensor and an indicator.
