Model Xs T 4,500 / 114.3mm - Casing Systems Brochure

This system is used for deep hole drilling when permanent casing installation and sub drilling are required with thick wall casing. The Xs T design has four (4) recessed portions to transfer impact directly from the driver to the crown, giving the necessary force to drill and drive down casing. The crown has a socket which fits over the casing for better welding alignment. This designed allows the driller to be able to drill the same diameter in bedrock as the casing I.D. with our special square bit, and allows the use of larger DTH hammers.
