Atlas Copco MAI SDA Self-drilling anchors provide a unique bolting solution for unstable ground conditions such as sand, gravel, silt, clay and soft to medium fractured rock formations. For projects with such ground conditions, Atlas Copco self-drilling anchors are the most productive reinforcement solution. The anchor rod features a hollow bore for flushing or for simultaneous drilling and grouting. The rod has a left-hand rope thread for connection to standard drill tooling. It is manufactured from API standard heavy wall steel tubing, cold rolled to form a standard ISO rope thread profile. The rolling process refines the grain structure of the steel, increasing the yield strength to produce a durable drill rod suitable for a range of applications.
