Double Casing Drilling System Manufacturer, Exporter, and Supplier
Superdrill Double head rotary percussive casing system utilizes a rotary head to drive the outer casing equipped with a tungsten carbide crown and a hydraulic drif_ter (top hammer) to drive the inner drill string equipped with a percussive drill bit. This is an excellent method for drilling straight holes in varying ground conditions. The water and compressed air can be both provided as power.
Our high-quality casing pipes are a vital component of our comprehensive drilling solutions. Designed to support and protect drill bits, these pipes play a crucial role in achieving the desired hole diameter while stabilizing drilling operations to prevent deviation. With customizable options available, our casing pipes are tailored to meet your unique drilling needs.
