R28 Full Threaded Hollow Self-drilling Anchor For Roof Bolting Product Description
Self-drilling anchors consist of a hollow anchor rod, anchor nut, anchor plate, anchor connector, drill bit, and stabilizer. Minetech's self-drilling anchors are a highly efficient solution, using a hollow rod and drill bit to drill holes in collapsed soil or loose rock. After the drilling operation, cement grout is injected into the hollow rod and the surrounding cavity, making it a highly effective solution.
