Normet Self Drilling Anchor® (SDA) – Self Drilling Rock Anchor

The main feature of the Normet Self-Drilling Anchor (SDA) system is the application of a single-use drill bit in combination with the rock bolt being used as a drill steel. Thus, the rock bolt is connected to the hydraulic rock drill by an adapter device and installed in the way a conventional borehole is drilled. The Normet SDA program consists of the following:

  • Single-use drill bits, which are available either hardened or with carbide inserts
  • Hollow, steel bars, with a continuous outside thread
  • Steel couplings, with a continuous inside thread
  • Steel nuts
  • Steel face plates
