Rock Drilling Tools
- The casing pipe is directly connected to the drilling rig, effectively preventing failure of casing advancement caused by casing or casing shoe breakage and ensuring smooth casing-follow drilling operations.
- Extended round-thread design prevents casing separation as drilling depth increases. The round threads offer superior compressive strength and torsional resistance compared with other thread forms.
- Triple-start thread design significantly reduces the risk of thread galling and seizure during long-term operation, ensuring easier disassembly after drilling.
Foundation pit support, ground reinforcement, slope stabilization, tunnel pipe roofing, and other anchoring and support applications.

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.
