The anchoring drilling rods are equipped with dedicated extended threads, which effectively prevent separation from the rod body during rotation.
The threads adopt a round-thread profile, offering improved geometric conformity, enhanced load distribution, and higher resistance to loosening under continuous drilling conditions.
The anchoring drilling tools are manufactured from thickened high-strength steel with reinforced thread designs, ensuring reliable self-drilling performance, high tensile resistance, and safe pull-out operations in steep slopes, tuff formations, and backfilled ground. These systems are widely adopted in deep excavation and slope stabilization projects.
The anchoring drilling tools are fully compatible with commonly used self-drilling anchor systems, providing secure connections, fast penetration rates, and reduced risk of thread disengagement. They are well suited for projects with high daily output requirements and tight construction schedules.
