Product Introduction

This rock drill coupling sleeve is forged from high-toughness alloy steel and treated with multiple quenching and surface hardening processes. It features high structural strength, excellent impact resistance and fatigue resistance, resisting cracking and deformation under high-frequency rock-drilling loads. Its internal and external threads are precisely CNC machined with standard tooth profile and accurate fit clearance. It connects drill rods tightly with good coaxiality, locks firmly and assembles smoothly, effectively preventing thread slipping and loosening during operation. It transmits impact energy and torque steadily with low power loss for continuous, efficient drilling. Compatible with T38, T45, T51 threaded drill rods, it suits hydraulic rock drills for mining, tunneling, slope support and quarrying. We are the original manufacturer with strict inspection. Custom sizes and thread specifications are available, with ready stock and formal invoices.
