Self-Drilling Rock Bolt

The self-drilling rock bolt is an anchor bolt system that performs drilling and grouting simultaneously. Its hollow bar design allows grout to be injected directly into the ground during installation. It is widely used in tunneling, slope stabilization, and ground improvement projects, especially in weak, loose, or water-bearing formations.

The system is modular and includes drill bits, couplers, and grouting accessories, providing reliable anchorage in challenging ground conditions.
