HT NT Drill Rods with Thin Wall Thickness for Conventional Drilling
Drill Rod & Accessories
ROSCHEN Group Limited 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 specifications 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 10ft. Many other lengths are available to meet
specific drilling needs.
