Dimensional Stone Drill Rigs. The dimensional stone drill rig has a more esoteric function that its other drill rig counterparts, in that its purpose is to drill precise holes in the ground in order to excavate for natural rock such as granite, limestone, marble, or sandstone so that it can be extracted and fashioned into blocks for construction.
