Abstract: The hole saw slug removal device is a device constructed to fit within a hole saw that provides for automatic ejection of waste slugs from within the hole saw. The hole saw slug removal device generally consists of two discs affixed on either end of a compression spring. The device is then inserted into the hole saw, and one disc retains the compression spring within the hole saw by locking onto the drill bit or against the inner surface of the hole saw. Upon operation of the hole saw, the spring compresses and the other disc is pushed down by the force of the sawing. After the sawing is completed, the spring decompresses, and the disc is pushed forward, automatically ejecting the waste slug that has become trapped within the hole saw. The slug removal device may lack one disc and instead be permanently affixed to a hole saw.

Abstract: 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.
