Top hammer shank adapters
Sandvik manufacture premium quality shank adapters for most brands of rock drills. While every component in the drill string is crucial, the shank adapter must be engineered to withstand the most extreme stress. Its function is to transmit impact energy from the rock-drill piston, as well as rotation torque, into the drill string withouth energy losses. It must withstand and transmit up to 6300 blows per minute from the piston continually, with great endurance and dependability.
