The HD25 core driving drilling system has been specifically developed for use under extreme operating conditions. Thanks to high-strength materials, precision manufacturing, and a robust design, the drill rods provide maximum stability and reliability.

The rope thread features seven thread turns and can usually be loosened quickly by hand. Its specially engineered design ensures reliable performance even when contaminated with dirt and debris. Compared with conventional systems, the significantly reduced time required to loosen the rod connections offers a major advantage, increasing efficiency on the job site.
