The Xs GT system is predominantly designed for piling, micro piling, anchor installation and other civil engineering applications where casing is left in the hole. This system can be used in moderate to deep hole drilling where ground conditions are severe. Overburden can be cased and sub-casing anchor sockets drilled into bedrock in one operation with the same driver-bit without removing the drill string. The driver has four (4) recesses which transfer impact directly to the crown, giving the necessary force to drill and drive the casing down. The drilling end of the driver bit, like conventional bits, is bigger than the body itself to provide clearance when drilling into bedrock.
