Optimize your high-frequency drilling with the HD712 T45 D51 590 shank adapter. Specifically engineered for HD712 series hydraulic rock drills, this 590mm striking bar features a heavy-duty T45 thread and a massive 51mm diameter. Fully carburized for superior torque resistance and perfect linear energy wave transmission in demanding underground mining and tunneling.
Key Performance Advantages
Massive D51 Rigidity: The 51mm diameter offers exceptional structural cross-section strength, eliminating shank flexing and ensuring superior hole straightness under heavy feed pressures.
High-Torque T45 Connection: Tailored for large-diameter drill strings, the T45 thread distributes rotational force evenly, preventing thread stripping or jamming in fractured ground.
Optimized 590mm Length: Precision-calibrated to match the HD712 piston stroke, ensuring peak impact energy transfer and protecting internal drifter components from harmful stress reflections.
Premium Fatigue Life: Advanced carburization and shot peening create an ultra-hard surface shell with a ductile, shock-absorbing core to withstand millions of continuous blows.
Primary Applications
Underground Mining: High-efficiency production drilling and long-hole stoping.
Tunneling & Drifting: Rapid face development and umbrella arch support systems in hard rock.
Quarrying & Bench Drilling: High-penetration blasting for civil engineering excavation.
