ABSTRACT:
A rotating diamond bit has a cutting face that includes a plurality of cutters and nozzles affixed thereto in spaced relationship respective to one another. A passageway extends through the bit body for flow of fluid through the bit connection to each of the nozzles. Each nozzle has an outlet orifice arranged to direct a lateral flow therefrom which impinges on the cutting face of each of the diamond compacts. The nozzles and compacts are arranged in groups, with there being a plurality of cutters and at least one nozzle in each group. The lateral flow from the nozzles diverges in a fan-like pattern to impinge directly onto the cutting face of each of the plurality of cutters.
