The Steerable Rock System for auger boring from McLaughlin navigates solid rock and difficult fractured-rock conditions. Engineered to operate in rock up to 25,000 psi, it has an open-faced design that allows fractured rock to be pulled into the cutting head, where it is crushed or swallowed, creating a consistent path. The system of both disc cutters and rock picks work to navigate varying rock conditions. It uses a fully rotational turntable, eliminating the need for a single main bearing that can seize up and freeze the head. 800/435-9340;
