Maximize your production drilling output with the heavy-duty COP1840 T45 D52 565 shank adapter. Precision-engineered as a direct replacement for COP 1840 series hydraulic rock drills, this 565mm striking bar features a high-torque T45 thread and a massive 52mm diameter. Fully carburized for superior fatigue resistance and maximum linear energy wave transmission in challenging mining and tunneling environments.
Key Performance Advantages
Massive D52 Structural Rigidity: The reinforced 52mm diameter delivers exceptional cross-sectional strength, completely eliminating shank flexing and deflection under high feed pressures.
High-Torque T45 Connection: Tailored for large-diameter deep-hole drill strings, the T45 thread provides a massive load-bearing surface, preventing thread stripping or "cold welding" under maximum rotational forces.
Premium Wear & Fatigue Life: Full-body carburization and intense shot peening create an ultra-hard surface shell to withstand front-head bushing friction, backed by a ductile, shock-absorbing core.
Primary Applications
Underground Production Mining: High-efficiency long-hole stoping, fan drilling, and ring drilling.
Heavy Tunnelling & Drifting: Rapid face development and complex umbrella arch support systems in extremely hard rock formations.
Bench Drilling & Quarrying: High-penetration blasting for civil engineering excavation and open-pit mining.
