Description:

The Minerza SP Series is engineered for maximum drilling speed and precision in demanding underground and tunneling operations. Its aggressive button geometry and elevated front design provide a 10–30% improvement in penetration rate, reducing drilling time by up to one hour per rig daily. Optimized flushing channels ensure efficient cuttings removal and smoother hole formation, while PowerCarbide-grade inserts deliver superior strength and fracture resistance. The SP Series enhances collaring accuracy, extends bit life, and minimizes maintenance downtime — achieving faster, cleaner, and more cost-efficient drilling.
