BC2’s Central Mining Equipment (CME) 85 drill rigs are true workhorses. With rotary torque of up to 20,000 lbs., it can turn larger diameter augers in almost any soil condition and with a 465 rpm rotational speed, it can also handle both rotary and coring jobs with ease. With 28,000 lbs. of pull-down force, the CME-85 can drill and set wells in deeper zones that many hollow-stem auger rigs cannot reach. These rigs can sample soil using either 140 lb. down hole hammer or auto hammer with split spoon, continuous, or SPT samplers. These rigs are capable of converting from hollow stem auger to mud rotary drilling when subsurface conditions change."
