Double Head Casing Drilling System Crown Drill Bits

Double Head Casing Drilling Systems

General Introduction:
The Double Head Casing Drilling Systems add flexibility to drilling in varying conditions. During drilling, water or compressed air are used as medium, and the discharge head makes the casing tube and drill rod rotate and penetrate. In addition to the benefits of increased flushing control, the inner and outer strings are able to be separately controlled, which greatly increases control over drilling operation. For deeper borehole applications the double casing drilling tools allows for a dual string drilling system with internal flushing, which maximizes the precision to target. The Double Casing Drilling method reduces risk, project time and produces optimal results. It can be widely used in drilling for grouting holes in projects such as cofferdam, foundation and geothermal well and etc..
 
Acedrills offers a full range of Double Head Casing Drilling Systems designed for specific drilling applications. They could be utilized in rotary-percussive mixed drilling or pure rotary only drilling.
