Abstract

A fluid jetting system for a rolling cone drill bit is provided in which a pressurized fluid spray (46) is directed tangentially across the main cutting inserts (22) and against the formation face so that when the drill bit is used in its most advantageous areas, such as the soft, medium-soft and plastic formations, the jetting system prevents "balling-up" of the cutters and greatly increases the drilling efficiency of the bit. <IMAGE>
