Product Description

 

RC Drill Rods & Reverse Circulation Double Wall Drill Pipes

 

REVERSE CIRCULATION DRILLING RODS

 

ROSCHEN reverse circulation heavy duty drill pipes outclass similar products on the market in both value and quality. Drilling Supply Store RC drill rods also provide the driller with excellent durability, thanks to the highest quality products which were used during the manufacturing process. Nearly 100% of our sales are direct to drilling contractors, whom openly specify our RC drilling pipes, because they last longer and drill deeper with the same air, offering the most value for the price. Additionally, our drill rods were designed specifically for RC drilling and are available in the reverse circulation drilling string configurations shown below.
