A system, method, and apparatus for the rigid alignment of drill bits with ergonomic drill motors is disclosed. An adjustable nosepiece adapter is mounted to the ergonomic drill motor adjacent the drill bit chuck. The adapter has a split clamp portion on its distal end for receiving a pressure foot. A guide bushing fits in the proximal end of the pressure foot. A coil spring is located in the pressure foot and allows the guide bushing to telescope within the pressure foot. The drill bit extends through the guide bushing, pressure foot, and adapter and is secured to the chuck. The distal end of the guide bushing fits closely within a hole in a template that is secured to the workpiece to provide holes that are more accurately formed in the workpiece. |
