Features:

1. Hollow full threaded design, it incorporates many kinds of functions, e.g. drilling, grouting, exhaust and anchorage. 
2. Drill bit:designed either for loose soil, rock or dense ground conditions.(EX/EXX/ESS-F).
3. Outside diameter of anchor rod can be from 25mm to 51mm for rope threaded

Application: suitable for crushing, weak surrounding rock, and high ground with surrounding stress large deformation complex geological conditions, it avoids the effect of hole collapse in construction.

Drill bit:

EX type: hardened cross bit for loose to medium dense conditions with small boulders
EXX type: TC cross bit for soft to medium rock formations.
ESS-F type: Button bit with TC inserts for medium rock formations.
