HD76 threads have larger, deeper coarse threads providing maximum durability and pullback as well as lower make-up torque. Joint strength is higher than the industry standard Q rating and equals the pullback rating of RQ thread.
INCREASED DRILLING CAPACITY
Rated for 3000 meters, the HD76 rod features a combination of exclusive heat treatments and a coarse thread design to provide the ultimate in pullback with lower make-up torque.
When ordered with optional grooves for communication inserts—Modular Electrically Connected Cable Assembly (MECCA)—the HD76 rod is the highest performing rod available for the gas drainage market.
THE STRONGEST, LONGEST LASTING HEAVY DUTY RODS AVAILABLE
Extensive competitive benchmarking proves Boart Longyear rods are better in rod joint load testing, bench and field bending, pull tests and make-break studies.
Whereas most manufacturers continue to use welding to produce composite rods with thick-walled ends, Boart Longyear incorporates V-Wall technology to produce its HD76 rods, eliminating the risk of weld cracks and possible failures.
LONGER ROD LIFE
Boart Longyear is the only manufacturer in the industry to case-harden pin threads. The result is a rod with 2x and more the thread life of competitors product.
Whether you need HD thread for large diameter drilling, Q™ thread for standard depths, RQ™ thread for deep holes, or WJ thread for conventional drilling, Boart Longyear has a variety of rods to meet all your drilling needs.
