The drill support assembly has a drill clamp for attaching the hand drill to a movable carriage under the control of a carriage actuating mechanism. An angular adjustment mechanism is provided in the drill support assembly so that the hand drill can drill holes at various angular orientations relative the support post. Various clamping members are provided for special jobs, such as drilling into a work piece of rectangular cross-section, or drilling a hole from the inside of a large cylindrical container.
