Powerroc Premium TCI Drill Bit for Extreme Hard Rock Mining and Quarrying

In abrasive mining environments, mud and sand contamination is the leading cause of premature bit failure. Our advanced sealed bearings block these abrasives, extending the bit's service life and reducing the frequency of tripping, which directly lowers your overall drilling cost per meter.

Absolutely. The bit body is forged from high-grade alloy steel and heat-treated for maximum structural integrity. Combined with our reinforced bearing system, it is specifically designed to withstand the severe shock loads and high WOB required for crushing extreme hard rock.

Our TCI cutters are made from premium tungsten carbide and are optimized in shape, size, and exposure. This unique design maximizes the crushing force against the rock while minimizing the risk of tooth breakage, ensuring a longer lifespan in highly abrasive strata.

The gauge pads are reinforced with super-hard tungsten carbide inserts and wear-resistant alloys. This acts as an active shield, preventing the side of the bit from wearing down prematurely. Maintaining the exact hole diameter is crucial for consistent explosive loading and preventing costly reaming operations.

No. We have engineered the hydraulic flow channels and nozzle placements to aggressively sweep the bottom hole. This high-velocity fluid flow efficiently flushes away sticky cuttings, keeping the bit face clean and maintaining a high Rate of Penetration (ROP).
