Description: This drill rig is used to core rock, and water is used to keep the bit cool, clean and lubricated. Rock coring is used for geotechnical and hydrological investigation as well as for well drilling in certain instances and also oil exploration. This rig has tires on it for easy mobility on the road, but many such drill rigs are fitted with crawler tracks for more access to remote areas. |
