The RockStar 9 features a 9 series matrix that takes versatility and performance to a new level. By adjusting drilling parameters, the RockStar 9 allows drillers to increase the penetration rate without sacrificing bit life. In shallow holes and underground drilling where conditions are variable, it provides high penetration rates. With a sufficiently powerful drill rig, drillers can push on the bit to get even higher penetration rates. In deep-hole, controlled drilling, the RockStar 9 stays sharp, even with lower weight on bit, providing excellent performance and extended bit life.
