self drilling anchor system SSR32 EX drill bit for self drilling anchor bolt
Introduction Of Hollow Drilling Mining Rock Grouting Anchor Bolt
1, Hollow Drilling Mining Rock Grouting Anchor Bolt consists of hollow core with continuous hot-rolled outside thread
2, Hollow Drilling Mining Rock Grouting Anchor Bolt can application as injection anchor without casing, especially for non-stable boreholes
3, self-drilling installation, utilization of the anchor bar as drill rod with a single-use drill bit
4, easy extension of the anchor bars by anchor coupler
5, grouting or development of the grout body either simultaneously with drilling using a rotary injection adapter or afterwards
6, assembly of the anchor head with the anchor plate and the nut, stressing and locking
