Underground Mining Safety - Kennametal

We know dust and noise are pervasive safety hazards underground and if they aren't controlled, can result in worker injury, lost production, and government fines. So we developed underground mining bits that produce less dust and designed underground drill bits that make less noise. Because nothing is more important than miner safety.
