Cutting-edge design
With a new asymmetric thread profile, the product is strengthened where it is most needed. By using different flank angles on the thread profile, stress levels are reduced in the critical area of the tightening flank, where many breakages begin. This stronger profile also allows an increased diameter of the bit end thread, boosting fatigue strength. Additionally, uncoupling is easier than in previous designs, saving both time and effort during underground operations.

Increased sustainability
These new tools benefit both the challenging underground drilling environment and workplace safety. The prolonged rod life means fewer rod changes and less heavy lifting for the driller. It is also a more sustainable choice for the environment.
