The life of this system is extended due to its geometry. The crown has an internal shoulder (doughnut) to receive impact directly from the driver providing the necessary force to drill and drive down casing. Having a &#;socket type&#; assembly fitting over the casing which allows for better welding alignment. No other system on the market will tolerate the use of a hammer as big as the Xs S drilling system
