A system, method, and apparatus for the rigid alignment of drill bits (23) with ergonomic drill motors (13,17) is disclosed. An adjustable nosepiece adapter (41) is mounted to the ergonomic drill motor adjacent the drill bit chuck (21). The adapter (41) has a split clamp portion (45) on its distal end for receiving a pressure foot (61). A guide bushing (71) fits in the proximal end of the pressure foot (61). A coil spring (65) is located in the pressure foot (61) and allows the guide bushing (71) to telescope within the pressure foot (61). The drill bit (23) extends through the guide bushing (71), pressure foot (61), and adapter (41) and is secured to the chuck (21). The distal end of the guide bushing (71) fits closely within a hole (83) in a template (81) that is secured to the workpiece (91) to provide holes that are more accurately formed in the workpiece (91). |
