How do drilling rigs work in hard rock?

2026-03-13
When drilling through hard rock formations, drilling rigs use diamond drill bits or carbide drill bits combined with high torque and low rotation speed. This allows the drill bit to grind through rock layers gradually while maintaining borehole stability.
