In underground and surface drilling, tooling failure is rarely a “bad batch” problem. It’s usually a mismatch between ground conditions, impact energy, flushing, and how the drill string manages vibration and wear. When rock is fractured, abrasive, or wet, drill steel and bit selection directly affects penetration, hole quality, and the cost per metre.
