Roschen manufactures drill rod with various thread types. Whether you need drill rod for standard depths, deep holes, HD thread for wide diameter or WJ for conventional drilling we have a drill rod to meet your drilling needs.
All drill rod products are manufactured from a Cold Drawn, high carbon steel tubing which is equal to or exceeds the minimum tensile strength required by the DCDMA standards. Use of this high quality steel assures a product that will withstand drilling and driving under the most severe conditions. There is 100% inspection of all threads during the manufacture of drill rod and drill rod couplings.
Our drill rods are all manufactured by CNC machines. They're made of high quality alloy steel. All our drill rods are complete heat-treated. Our rods will be also suited to drill deep holes. From drillers' feedback, our rods have drilled up to 2000 meters depth.
