The Xs T V2.0 system can be used with any size casing

but is predominantly designed for thick wall casing.

The Xs T V2.0 system has four (4) keyways to transfer impact directly from the driver to the crown giving the necessary force to drill and drive the casing down. The lugs (locking mechanism) are bigger and offer a greater impact surface increasing the life span of the system considerably. Depending on the model, the impact surface can be increased by up to 4 times that of the standard version. The crown has a socket assembly which fits over the casing for better welding alignment. The drilling diameter in bedrock will be slightly reduced compared to the Xs drill systems of the first generation.

Driver Bit

The driver bit is the device that transfers impact and rotation to the crown bit for drilling. The driver bit locks into four flats on the casing crown and they act together as a standard drill bit, both the driver bit and the crown have tungsten carbide buttons. The Driver bit drills a pilot hole below the crown to guide the direction of the casing in rough drilling. Afterwards this pilot space below the crown allows the square bit to turn without touching the crown.

Crown Bit

The crown bit is a two-piece unit permanently connected together. The upper part is welded to the casing, and the lower part, which has Tungsten Carbide is free to rotate with the driver bit.

  • Impact zone: Direct energy from the hammer is transferred to the crown bit through four (4) recesses formed by the locking surface.
  • Evacuation: Two (2) big air holes are drilled in the face of the bit (drilling end). Those holes are directly connected to two (2) large flushing air ways, this transfer the drill debris from the drilling end of the driver up in the casing. To help the evacuation of debris, two (2) smaller air holes in the flushing air ways, gives the cuttings some velocity.

This model also comes with a “rotational-crusher zone”. That protective zone is placed at the end of the flushing air ways, just under the hammer spline drive. This zone (patent pending) is to improve the evacuation by preventing accumulation of rocks and gravel at a recess point. By turning the driver against a fix casing, the rock is crushed in smaller particles and then evacuated through the casing.
