Details

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.

In steep slopes and deep excavations with single-side anchoring, how do the anchoring drilling tools perform in terms of tensile resistance and self-drilling capability?

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.

How do high-penetration anchoring drilling tools integrate with self-drilling anchor systems to ensure construction efficiency?

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.
