Product Features:
1.With a bit at the anchor head, it is easy to cut through various rocks.
2.With the high-strength coupling elongated by mechanical cutting technology, this self-drilling anchor can be used at the place with narrow space, achieving the aim of rock reinforcement with extra-long anchor.
3.It’s unnecessary to take the measure of sleeve protecting and pregrouting to drill the holes in condition of various surrounding rocks since this anchor embodies drilling, grouting and anchoring as a whole, and significant anchoring and grouting are achieve
