Ame Drill Self Drilling Anchor (SDA) Rock Bolt

The self-drilling anchor (SDA) rock bolting system is a highly up-to-date, reliable, and high-efficiency anchoring system that is widely used for tunneling bolting, ground supporting, soil nailing, slope stabilization, and micro-piling. Our self-drilling rock bolting system has the following advantages:

1. Each of our rock bolts is manufactured from premium steel and the most advanced technology, which ensures our quality meets international standards or is even better.

2. Self-drilling rock bolting system eliminates the requirement of a cased borehole; soil drilling, grouting, and anchoring can be finished simultaneously.

3. Self-drilling rock bolts can be used only for temporary support but also for permanent support in many applications, like tunneling support, micropiling, soil nailing, etc.
