    2015-1-5 · Rotary-percussion drilling Method: In very hard rocks, such as granite, the only way to drill a hole is to pulverize the rock, using a rapid-action pneumatic hammer, often known as a 'down-the-hole ham-mer' (DTH). Compressed air is needed to drive this tool. The air also flushes the cuttings and dust from the borehole.
