Maximize your deep-hole drilling output with the heavy-duty YH80A T45 D51 495 shank adapter. Precision-engineered as a direct replacement for YH80A series high-power hydraulic rock drills, this 495mm striking bar features a high-torque T45 thread and a massive 51mm diameter. Fully carburized for ultimate shearing resistance and maximum linear energy wave transmission in challenging hard rock mining.
Key Performance Advantages
Massive D51 Structural Rigidity: The reinforced 51mm diameter delivers extreme cross-sectional strength, completely eliminating shank flexing and deflection under high feed pressures in tough geological strata.
Robust T45 Thread System: The T45 thread configuration provides a massive load-bearing surface, allowing the YH80A drifter to deliver its maximum rotational torque without the risk of thread stripping or thread "cold welding."
Premium Wear & Fatigue Life: Full-body carburization and intense shot peening introduce high compressive stress, creating an ultra-hard exterior shell to withstand front-head bushing friction, backed by a 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 extremely hard rock formations.
Bench Drilling & Quarrying: High-penetration blasting for civil engineering excavation and open-pit mining operations.
