Brief introduction:
The dual-head casing drilling system increases drilling flexibility under different conditions.

During drilling, with water or Compressed air as the medium, the discharge head rotates the casing and drill pipe through. In addition to the benefits of increased flushing control, the internal and external string can be controlled separately, which greatly increases control over drilling operations.

For deeper drilling applications, dual-casing drilling tools allow internal flushing of the dual-string drilling system, maximizing the accuracy of the target. The double casing drilling method reduces the risk, shortens the construction period and achieves good results. It can be widely used in cofferdam, foundation, geothermal well and other engineering grouting hole drilling.

We offer a full line of dual-ended casing drilling systems designed for specific drilling applications. It can be used in rotary percussion mixed drilling or pure rotary drilling.
