Maximize drilling efficiency with the HD609 T45 D45 620 shank adapter. Specifically engineered for HD609 series hydraulic rock drills, this 620mm striking bar features a heavy-duty T45 thread and a robust 45mm diameter. Fully carburized for superior torque resistance and energy transmission in hard rock mining.
Key Performance Advantages
High-Torque T45 Connection: The T45 thread provides a massive load-bearing surface, preventing thread stripping under heavy rotational torque.
Perfect Weight-Matching: The 620mm length is calibrated to match the HD609 piston stroke, ensuring linear energy waves and reducing internal drifter wear.
Reinforced D45 Body: The 45mm diameter offers exceptional structural rigidity, eliminating flexing and ensuring superior hole straightness under high feed pressure.
Premium Fatigue Life: Full-body carburization and shot peening create an ultra-hard exterior shell with a ductile, shock-absorbing core.
Primary Applications
Underground Mining: Long-hole stoping and production blast holes.
Tunnelling: Rapid face development and umbrella arch systems.
Bench Drilling: High-penetration quarrying and civil excavation.
