Rock Drilling Tools Product Advantage

This drill rod is forged from a single piece of high-strength alloy structural steel, exhibiting uniform material properties, excellent toughness, and fatigue resistance. It can operate stably under high impact and high torque conditions, and is not prone to bending or breakage.

The rod body undergoes precision heat treatment and surface strengthening processes, effectively improving wear resistance, impact resistance, and corrosion resistance, significantly reducing downhole wear and extending overall service life.

The threaded joint is precision-machined and rigorously matched, ensuring high connection accuracy, excellent sealing, and a secure, non-loose connection. This effectively reduces rod breakage, slippage, and other malfunctions, ensuring continuous operation efficiency.
