Diamond Drilling

This method is utilised when drilling hard rock.  Diamond drilling employs an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock. Drillwest’s Diamond rigs can be used for Diamond drilling or as a part of a multi-combination rig.
