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