Maximize your production drilling output with the HL700 T51 D52 600 shank adapter. Precision-engineered for HL700 series hydraulic rock drills, this 600mm striking bar features a high-torque T51 thread and a robust 52mm diameter. Fully carburized for superior shearing resistance and optimal energy wave transmission in heavy hard rock mining.
Key Performance Advantages
Enhanced D52 Body Rigidity: The 52mm diameter provides high cross-sectional strength, preventing shank flexing and deflection under high feed pressures during deep hole drilling.
Ultra-Torque T51 Threading: Engineered for large-diameter drill strings, the T51 thread maximizes rotational force transmission and prevents thread "cold welding" or stripping in fractured ground.
Premium Wear & Fatigue Life: Full-body carburization and shot peening create an ultra-hard surface shell to withstand front-head bushing friction, backed by a highly ductile 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 hard rock.
Bench Drilling: High-penetration blasting for civil engineering excavation and open-pit quarrying.
