If you have a special rock garden or landscaping project that requires holes drilled in some of the rocks, rent or purchase a special drill press equipped with diamond bits. These machines are designed to drill out holes in hard and uneven surfaces with precision. It is advised that water be poured onto the rocks during the process to keep the bits from overheating or the rock from heating internally and splitting.
