The self-drilling anchor system is an advanced geotechnical solution designed for efficient ground reinforcement and stabilization. The system comprises several key components, including a hollow anchor bar, nut, bearing plate, coupler, centralizer, and drill bit. By integrating drilling, grouting, and anchoring into a single process, this system is particularly effective in challenging ground conditions such as fractured rock masses and unstable surrounding strata where conventional drilling methods often fail.
With its versatility, efficiency, and reliability, the self-drilling anchor system is a preferred choice for modern geotechnical and construction projects, offering a cost-effective and high-performance solution for ground stabilization and reinforcement.

· Slope stabilization
· Anchoring for rockfall barriers
· Bolting, especially in underground works such as road and rail tunnels and mining
It is particularly valuable for pre-construction support, improving the stability of soil and rock masses before excavation or structural work begins.
The hollow bar itself acts as the reinforcing element, eliminating the need for additional rebar insertion.
The continuous threading along the bar ensures optimal adhesion of cement grout, enhancing load transfer.
Manufactured from high-grade steel with a high elastic limit, the system withstands drilling forces and long-term structural loads.
Faster installation reduces labor and equipment expenses.
The system reduces material spoilage and environmental impact compared to traditional methods.
For additional safety, especially for international shipments, these self-anchor drilling system tools will be packed in standard package, ensuring superior strength and resistance to rough handling, moisture, and other potential hazards during long-distance transportation.
