Roschen CDC System

Roschen CDC system can be used to install casings in many different types of overburdens, and in all types of natural formations. The CDC system drills straight holes and penetrates boulders easily. The system is designed for use with permanent casings, which are welded together progressively during drilling and left in the hole. It can be used to drill and case comparatively deep holes, depending on the application, hole inclination, and ground conditions.

The system consists of a pilot bit and a concentric ring-bit/casing shoe assembly. The ring bit and casing shoe are delivered as a single unit, connected to each other via a rotary joint. These two components, together with a DTH hammer, the drill pipes and the casings, make up the complete system.
