Excavator Mounted System & Components
The HEM (Hydraulic Excavator Mount) is the most popular drilling attachment.The stable excavator base with long boom combines to form an excellent drilling platform. The HEM receives hydraulic power from the excavator’s Auxiliary Hydraulic circuit.
Our drifters have an internal dampening system that only allows for full power when the drill string is engaged. A built-in swivel accepts air, water or grout for all types of drilling including the installation of the popular hollow bars.
