36mm 7 Degree Taper Button Drill Bit for Hard Rock Mining Blast Hole Drilling
This Henglong 36mm 7-degree tapered button drill bit is specifically designed for high-strength hard rock mining and blasting hole operations. It combines precision engineering, exceptional durability, and superior drilling efficiency for demanding mining applications.
Key Advantages
7° Tapered Shank Design: Ensures reliable power transmission with tight, non-slip connection to matching drill rods. The precision-machined tapered surface eliminates component gaps, minimizes torque loss during high-load drilling, and prevents accidental detachment. This connection method enables tool-free assembly and disassembly by one person, reducing tool change time by up to 20%.
Optimized Carbide Button Configuration: Specifically engineered for hard rock penetration. The spherical button shape concentrates impact force on smaller contact areas, allowing efficient penetration of hard, abrasive rock formations with minimal resistance. The staggered arrangement evenly distributes drilling pressure, reducing vibration and drilling deviation.
Reinforced Alloy Steel Construction: The drill bit body is forged from high-quality 42CrMo alloy steel and undergoes two-stage quenching and tempering heat treatment, achieving tensile strength up to 1150 MPa with excellent impact toughness for long-lasting durability.
Adaptable to specific mining conditions and environments
Compatibility & Applications
This drill bit is compatible with both pneumatic and hydraulic drilling rigs commonly used in underground and open-pit hard rock mines. It operates reliably in extreme temperatures and humid underground environments, making it suitable for the most challenging mining conditions.
Quality Assurance
Each Henglong 36mm 7-degree tapered button drill bit undergoes rigorous factory testing, including carbide button hardness verification, tapered shank dimension calibration, and dynamic impact resistance testing. This comprehensive quality control ensures maximum drilling efficiency and minimizes the risk of equipment failure.
