Abstract: This hand tool is a portable tool, to be used on a construction site to drill pilot holes for the standard 41/2" hinge used on doors in the majority of commercial buildings. It's light-weight, small and powered by any 3/8" drill motor. Base of tool is used to align the drills in place on the routed out section of door or jamb. The 4 hole configuration the tool has is a standard location used by the main door hinge manufacturers. The main advantage of the tool is the accuracy of the holes drilled. The labor time is cut by 75% over the old conventional way of drilling the holes in the hard wood one at a time for the accommodation of the screws that hold the hinge in place.
