Optimize your high-frequency drilling stability with the heavy-duty COP1838 R32 D52 525 shank adapter. Specifically engineered for COP 1838 series hydraulic rock drills, this 525mm striking bar features a standard R32 thread and a massive 52mm diameter. Fully carburized to prevent deflection and ensure optimal linear energy wave transmission in challenging ground support and tunneling environments.
Key Performance Advantages
Massive D52 Reinforced Body: The large 52mm cross-section delivers extreme structural rigidity, preventing shank flexing and bushing misalignment within the drifter's front head under high feed pressure.
Precision R32 Threading: Machined to strict international tolerances, the R32 thread ensures seamless, tight coupling with R32 drill strings and quick uncoupling during high-frequency drifting cycles.
Premium Wear & Fatigue Life: Full-body carburization and intensive shot peening generate beneficial compressive stresses, creating a "glass-hard" exterior shell (58-62 HRC) backed by a ductile, shock-absorbing core.
Primary Applications
Specialized Ground Support: Precision-aligned hole drilling for heavy-duty rock bolt and roof anchor installation.
Underground Drifting & Tunnelling: Stabilized face drilling in variable, fractured, or abrasive rock formations.
Limited Access Deep-Hole Drilling: Maintaining superior hole straightness in confined spaces requiring maximum tools guidance.
