ABSTRACT:
An adapter for a hand-operated power driven screwdriver and accommodating at least part of the barrel. A drill bit chuck is rotatably mounted in the adapter, and the chuck is driven by the engagement of the tip end of the screwdriver with a screw head mounted in the end of the rotatable chuck on the axis of rotation. The chuck accommodates a cutting tool, such as a drill bit, for drilling guide holes for screws into a surface. The adaptor can be removed from the power driven screwdriver to drive screws into the guide holes.
