Drilled to 150' with the rigs in sandstone / claystone utilizing an air compressor. They can go to 400' in light alluvials (Clay, Silts, Sands, some gravels.). They are currently retrofitted to switch seamlessly from Air Rotary to Mud Rotary. Drilled 6" to 10" boreholes with them. Can switch between air & mud rotary.
