Underground Taper Drill Rod

Product Overview Underground Taper Drill Rod is a core member of Tapered Drilling Tools, designed for underground rock drilling operations. It falls into Fully carburized taper drill rods, transmitting impact force and rotary torque efficiently. It can be assembled with Coupling Sleeve to link different rod sections and can cooperate with Round Extension Drill Rod to build extended drill strings. Key Advantages Made of high-quality alloy steel with full carburizing heat treatment, this drill rod features excellent impact toughness and fatigue resistance. The hexagonal rod body enhances torque transfer, and the reinforced shoulder structure effectively prevents fracture under frequent underground impact, lowering maintenance frequency and improving drilling continuity. Detailed Features Precision tapered end ensures quick and stable connection. It can be combined with Round Extension Drill Rods to achieve deeper borehole construction. Threaded Coupling Sleeve serves as optional fitting…
