Designed for tunneling, horizontal drilling, micropiling and several other applications, Symmetrix is a concentric drilling system from Atlas Copco with retrievable pilot bits for casings 3 inches to 48 inches. The Symmertrix system can drill in any direction and in any type of ground condition, including sandy or rocky terrain, to depths beyond 100 meters. Compatible equipment includes DTH and top-hammer rigs. Pile boring rigs, exploration rigs and cranes also can be adapted to use Symmetrix.
