  • Rock drill extension rods, as the name suggests, are elongated tools designed to extend the reach of rock drills, enabling workers to bore deeper and more precisely into hard rock formations. These rods are typically fabricated from high-grade steel alloys to withstand the intense forces generated during the drilling process. Their resilience is further bolstered by thermal treatment procedures that ensure a balance between toughness and flexibility, preventing fractures under pressure.
