Maximize your drifting and tunneling efficiency with the RD520 T38 D45 525 shank adapter. Precision-engineered as a direct replacement for Sandvik RD520 high-power hydraulic rock drills, this 525mm striking bar features a heavy-duty T38 thread and a robust 45mm diameter. Fully carburized for superior fatigue resistance and perfect linear energy wave transmission in hard rock environments.
Key Performance Advantages
High-Torque T38 Connection: Designed to handle large rotational torque, the T38 thread distributes force evenly, preventing thread stripping or jamming during deep-hole operations.
Reinforced D45 Structural Rigidity: The 45mm body diameter provides extreme resistance to bending and axial fatigue under high feed pressures, ensuring superior hole straightness even in fractured rock formations.
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 Drifting & Tunnelling: Ideal for Sandvik jumbos performing rapid face development in mining and civil engineering.
Production Drilling: Reliable and consistent performance for medium-to-long hole blast hole patterns.
Heavy Ground Support: Precision-aligned hole drilling for the installation of T38 rock bolts and anchors.
