Drill Rod & Accessories

 

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.

 

As required, all thread specification on drill rod and drill rod couplings meet the thread standards set by DCDMA and will therefore interchange with products manufactured by other DCDMA members.

 

Drill rod couplings are made of AISI 4140 alloy steel and are heat treated to assure durability. Drill rod may be purchased in stock sizes of 5ft or 10 ft. Many other lengths are available to meet specific drilling needs.
