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.

The coupling enables direct end-to-end energy transmission between
each bar, reducing losses and ensuring maximum percussive energy at
the drill bit. To enable the correct seating of each bar within the
coupler, all bars are chamfered with precision to enable the bar
ends to have face-to-face contact.
