Abstract: A screwgun extension for extending the reach of a screwgun to permit a user to turn screws located a greater distance from the screwgun than could be reached with the rotating chuck of the screwgun alone. The screwgun extension includes an elongate tube with opposite open proximal and distal ends. The proximal end of the tube is designed for receiving a chuck of a rotary tool therein. The tube has an arcuate bulbous collar adjacent the proximal end of the tube which has a convex outer surface outwardly extending from the exterior surface of the tube. An elongate drive shaft is disposed in the lumen of the tube. A first end of the drive shaft is extended towards the proximal end of the tube. A second end of drive shaft is outwardly extended from the distal end of the tube The first end of the drive shaft is designed for clamping between jaws of a chuck of a rotary tool inserted into the proximal end of the tube such that rotation of the chuck rotates the drive shaft.
