Product Description


Full threaded steel self drilling rock bolt / Hollow anchor bar / Anchor rods
The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs
drilling,anchoring and grouting in a single operation. Self drilling anchor system is mainly used in slope stabilization,
tunneling pre-support, foundations with micro piles etc projects.
Advantages and Characteristics as below:
1. No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
2. Fast drilling and installation, because drilling, installation and grouting are in a single operation.
3. Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of
bondwith the borehole gout.
4. The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
5. Continuous threads ensure the bars can be cut and coupled at any point, or extended.
6. Different anchor bits are available for different ground conditions.
