Abstract: The apparatus comprises a cylindrical casing or housing with an interior passageway in which is mounted a fluid divider comprising three air divider legs each of which is a tapered plate formed with a concave cavity or air scoop with curved upper edges that are joined together in the center so that the legs diverge downwardly and outwardly in the drill string passageway of the cylindrical housing. The legs support a divider hood dome on which is mounted three separate curved plates defining three air channels. The fluid is directed into the concave scoops then into channels that lead to the outside of the housing in an upwardly direction. Fluid also spills over the air divider scoops and travels onto the bit, cooling the bit and chip removal from around the rollers.
