A support fixture for a hand-held power tool includes a base plate and a guide plate assembly supported for movement relative to the base plate to bring the working end of the power tool into contact with a workpiece on which the base plate is supported. The guide plate assembly includes a tool support housing configured for supporting the body of the power tool, and an overthrow nut assembly for threaded engagement with a threaded portion of the power tool adjacent the working end of the tool. The fixture includes a guide bushing that is top-loaded into a bushing collar defined in the base plate, in which the guide bushing is configured to engage a template supported on the workpiece. A threaded plug holds the guide bushing within the bushing collar.
