The performance of a rock drill shank is directly proportional to the efficiency of the drilling process. Its ability to transmit energy from the drill rig to the bit is crucial in breaking down rock. The shank's hardness and resilience allow it to absorb and transfer the percussive force generated by the drill hammer, enabling the bit to penetrate the rock surface effectively The shank's hardness and resilience allow it to absorb and transfer the percussive force generated by the drill hammer, enabling the bit to penetrate the rock surface effectively The shank's hardness and resilience allow it to absorb and transfer the percussive force generated by the drill hammer, enabling the bit to penetrate the rock surface effectively The shank's hardness and resilience allow it to absorb and transfer the percussive force generated by the drill hammer, enabling the bit to penetrate the rock surface effectivelyrock drill shank.
