In diamond drilling, bit load (weight on bit), rotational speed (RPM), and penetration rate (ROP) form an interdependent system. Increasing one parameter without considering the others often leads to accelerated diamond wear, reduced footage, or sudden bit failure. Decades of laboratory testing and field experience, summarized in classic references such as the Diamond Drill...

The function of waterways in a diamond drill bit is straightforward:to remove cuttings and heat from the diamond cutting points as efficiently as possible. Water pressure and water volume are both critical. Excessive pressure combined with high rotational speed can generate unnecessary heat, accelerate matrix wear, and reduce diamond life. Insufficient flow, on the other hand, leads to poor...
