Self drilling anchor bolt embodies drilling, grouting and anchoring
as a whole. Widely used as an efficient anchoring means, in tunnel
pre-support, slope stabilization, coast, mine, water conservancy
projects, building foundation, roadbed reinforcement and geological
diseases treatment such as landslip, crack, sink age. Its
irreplaceable in narrow construction environment.

Drill bits are cutting tools used to create cylindrical holes,
almost always of circular cross-section. Bits are held in a tool
called drill, which rotates them and provides torque and axial
force to create the hole. You can choose different drill bits for
various ground condition. It is especially efficient and fast when
drilling in hard and medium-hard rock.
1. It has a high hardness and wear resistance.
2. It has good heat resistance and corrosion resistance.
3. Advanced geometric design for faster penetration.
