Maximize your fleet efficiency with the multi-compatible YH65 YH70 YH80A T45 D51 500 shank adapter. Precision-engineered to fit YAMAMOTO YH65, YH70, and YH80A hydraulic rock drills, this 500mm striking bar features a heavy-duty T45 thread and a massive 51mm diameter. Fully carburized for ultimate torque resistance and maximum linear energy wave transmission in demanding hard rock mining.
Key Performance Advantages
Multi-Model Versatility: Tailored to meet the exact internal tolerances of YH65, YH70, and YH80A hammers, allowing mining contractors to reduce inventory overhead by using a single shank for multiple drill rigs.
Massive D51 Structural Rigidity: The 51mm diameter delivers extreme cross-sectional strength, completely eliminating shank flexing and deflection under intense feed pressures.
High-Torque T45 Connection: Designed for large-diameter deep-hole drill strings, the T45 thread handles massive rotational forces without thread stripping or jamming.
Premium Fatigue & Wear 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 mass excavation.
Heavy Tunnelling & Drifting: Rapid face development and complex umbrella arch support systems in hard rock.
Bench Drilling & Quarrying: High-penetration blasting for civil engineering excavation and open-pit mining.
