In an embodiment, a drill nozzle includes a housing having a bristle brush ring attached. The housing of the drill nozzle may include an air intake, multiple coolant inlets, multiple coolant jets, a vacuum tube, and mounting flanges. The air intake may provide a thrust-vectored down draft into the vacuum tube. The coolant inlets may receive coolant fluid that may be expelled from the coolant jets towards a drill bit. Drilling debris and coolant fluid may be contained inside the bristle brush ring preventing damage and soiling of surrounding structures and areas and may be extracted with the vacuum tube. The drill nozzle may be attached to a drill motor unit of a numerically controlled drill jig, enabling the use of such numerically controlled drill jig for drilling high quality holes effectively into non-flat surfaces, for example, the leading edge extension spar of the F-18 aircraft.

A portable fastener delivery system is provided that comprises an automated unloading mechanism that removes fasteners from a fastener storage device and delivers the fasteners through a delivery conduit to a work station. Generally, the portable fastener delivery system is mobile throughout a production facility so that fasteners may be delivered to a plurality of work stations. In operation, a signal is transmitted to a control system requesting a specific fastener configuration, and the control system causes positioning of the unloading mechanism adjacent the fastener storage device. A pneumatic source is then activated to cause the unloading mechanism to remove a fastener from the fastener storage device using a vacuum generator, and once the fastener is removed, the fastener is transported through a delivery conduit to the work station using pressurized air from the pneumatic source through a flexible fastener delivery tube.
