THE R32-ROD-RD32 EXTENSION ADVANTAGE:

  • Linear Energy Wave Transmission: Machined from premium round hollow alloy steel, the R32-ROD-RD32 ensures that percussive shockwaves travel in a perfectly straight line, minimizing vibration feedback and protecting the drifter's piston.

  • Balanced Carburized Core: Our full-length uniform carburization technology creates a high-hardness outer protective matrix to eliminate thread wear, while maintaining a flexible inner core to absorb extreme bending stresses during deep-hole tracking.


Transmitting high-frequency percussive impact energy smoothly into deep-hole layouts requires an extension string engineered for precise linear alignment and exceptional thread longevity. Bloom's R32-ROD-RD32-MM-EXT is a premium round 32mm male-to-male extension drill rod explicitly developed for long-hole production, benching, and under-stoping operations in demanding underground mining environments. Forged as a single continuous piece from high-grade hollow alloy steel mass and finished under strict CNC machining protocols, this heavy-duty round rod minimizes bending deflection while ensuring maximum flushing efficiency through its uniform internal fluid path.

Engineered to withstand relentless hydraulic percussion on modern multi-stage drilling rigs, the entire body of the R32-ROD-RD32-MM-EXT undergoes a state-of-the-art full-length gas carburization process. This advanced heat treatment infuses the R32 male thread profiles with a deep, wear-resistant outer armor that prevents premature stripping, galling, and loose coupling rattle under intense rotation. By balancing a high-strength surface structure with a highly flexible core, our rod layouts absorb punishing cyclical flex-shocks effortlessly, lowering total tool consumption costs and protecting your valuable R32 button or reaming arrays inside irregular rock strata.
