High Strength Alloy Steel Integral Drill Rod With Chisel Tip For Hard Rock And Integral Forged
The Ultimate One Piece Rock Drilling Solution
Henglong Integral Drill Rods (also recognized as single chisel all steel bits) represent the pinnacle of durability for percussive drilling. Unlike modular systems, these tools feature a seamless, one piece forged construction where the bit and the rod are a single entity. At the business end, a high grade tungsten carbide chisel insert provides the hardness required to dominate high frequency impacts and intense torque from modern pneumatic and hydraulic rock drills.
Core Advantages of Our Integral Drill Steel
Maximum Energy Transmission: The integrated design eliminates the " energy leak " often found in threaded couplings. By delivering the hammer's impact force directly to the rock face, our rods significantly accelerate the Rate of Penetration (ROP) in medium to hard strata.
Unmatched Structural Integrity: By removing connection points, we've eliminated the 1 cause of down the hole fractures. This rigid, monoblock structure ensures perfect borehole alignment, even in deep hole operations or restricted underground spaces.
Industrial Grade Alloy Materials: We utilize elite high strength alloys like 42CrMo and 45CrNiMoVA. Combined with proprietary precision heat treatment, our drill rods offer industry leading resistance to metal fatigue and abrasive wear.
Cost Efficient Maintenance: The classic chisel tip geometry is designed for longevity. When the cutting edge dulls, it can be easily resharpened — manually or with a machine — drastically lowering your total cost per meter drilled.
Versatile Applications in Heavy Industry
Mining Operations: Essential for blast hole drilling in both surface / open pit and deep underground mines.
Infrastructure Tunneling: Ideal for high speed excavation and bolting support in railway, subway, and highway projects.
Dimension Stone Quarrying: Precision extraction of high value materials like granite, marble, and sandstone.
Civil Engineering: Reliable performance for foundation reinforcement, pavement demolition, and specialized anchor hole drilling.
