RC DRILL ROD

Starockdrill employs a unique friction welding process to manufacture drill rod joints, ensuring exceptional safety performance at the highest level.
We carefully select premium materials and apply surface heat treatment, ensuring the drill rods' stability and reliability in terms of wear resistance and strength.
The reverse circulation drill rods feature internationally standardized threads, providing ease of operation.
To meet your specific requirements, Starockdrill offers custom thread types and lengths, catering to the diverse needs of all our customers.

Reverse Circulation drill rod (also called dual-wall drill pipe) comprises an outer and inner pipe with a sealing system (usually 0 Rings) to keep the drill string pressurized. 

As RC drill rods are subjected to high wear in the drilling process STAROCKDRILL use only the high quality hardened alloy steel for the both rods and tool joints.

Our reverse circulation drill rods and drill pipe consist of  hardened alloy steel tool joints with heavy duty seamless drill pipe and high tensile wear resistant Inner Tubes. Drawing on our years of experience in the design and manufacture of tough and wear resistant RC drill rods, every aspect of material and production management is optimized. The result is premium quality reverse circulation drill pipes that keep your RC drill rig efficiently producing day after day. RC drilling companies across the globe know they can rely on Sinodrills reverse circulation drill pipe.

You can be sure that RC Drill Pipe will still be going strong when others have worn out.
