Abstract: A power drill attachment for exerting pressure through the drill bit onto the workpiece has a toggle linkage to provide a mechanical advantage of such sensitivity as to permit the operator to easily and quickly control the amount of pressure being exerted throughout the drilling operation. The attachment is especially adapted for use when drilling holes in door and window frames, through floor joists, studs, rafters and other building framework.
