The recent machines are driven by electricity. Diamond bits drill by wearing out the rock under the bit. They produce very small cuttings called rock flour. Diamond bits can drill the hardest rock but they drill slow and are very expensive. 5m/hour is a realistic average penetration rate for holes <1000m.
