Abstract
A rotary drill bit comprises a bit body carrying a plurality of cutting elements and a main conduit for conducting drilling fluid. A plurality of nozzle bodies is rotatably seated in bores of the bit body. Each nozzle body includes a plurality of passages extending therethrough for conducting drilling fluid in such manner that the exiting fluid causes the nozzle body to rotate about its longitudinal axis. The exiting fluid is thus distributed in a wider pattern.
