Maximize your high-power drilling efficiency with the HC120R T45 D45 520 shank adapter. Specifically engineered for HC120R series hydraulic rock drills, this 520mm striking bar features a reinforced T45 thread and a robust 45mm diameter. Crafted from premium-grade forged alloy steel and fully carburized, it delivers exceptional linear energy wave transmission and superior resistance to shearing and fatigue in the toughest geological formations.
Product Specifications
Drill Compatibility: Fully optimized for HC120R hydraulic drifters
Robust T45 Thread System: The T45 thread provides an expanded cross-sectional and load-bearing surface area compared to standard T38 threads. It allows the HC120R to deliver its maximum rotational torque without the risk of thread stripping, while ensuring easier uncoupling after long, high-pressure drilling cycles.
Reinforced D45 Structural Rigidity: Under high feed pressures, shank flexing leads to catastrophic failure. The 45mm body diameter provides extreme resistance against bending and axial fatigue, maintaining superior hole straightness even when drilling through highly fractured or variable rock strata.
Premium Metallurgical Process: Every shank adapter undergoes a strict multi-stage full-body carburizing process followed by intense shot peening. This introduces beneficial compressive stresses, creating a "glass-hard" outer shell to withstand front-head bushing friction while preserving a highly ductile core to absorb millions of cyclic stress impacts.
Primary Applications
The HC120R T45 D45 520 is the professional choice for:
Heavy-Duty Tunnelling: Fast-paced drifting and face development in hard rock formations.
Production Mining: Consistent performance and precise hole alignment for deep long-hole blast patterns.
Bench Drilling: Maintaining high penetration rates (ROP) in large-scale quarrying and open-pit mining.
