Maximize your drilling productivity with the HC109 T38 D45 490 shank adapter. Specifically engineered for HC109 series hydraulic drifters, this 490mm striking bar features a high-torque T38 thread and a robust 45mm diameter. Crafted from premium-grade alloy steel and treated with advanced carburization, it delivers exceptional energy wave transmission and superior resistance to fatigue during heavy-duty mining and tunneling.
Product Specifications
Drill Compatibility: Fully optimized for HC109 hydraulic drills
Key Advantage: Built for high-frequency impact and deep-hole drill strings
Core Advantages of the HC109 T38 D45 490
Robust T38 Thread System: The T38 thread provides a larger contact and load-bearing surface than standard R-threads. It allows for much higher rotation torque transmission and easier uncoupling after high-pressure drilling, preventing thread jamming.
Reinforced D45 Structural Rigidity: The 45mm body diameter provides extreme resistance to bending and axial fatigue under high feed pressure. This minimized deflection ensures superior hole straightness even when drilling through highly fractured or uneven rock formations.
Advanced Heat Treatment & Shot Peening: Every shank adapter undergoes an intensive carburizing process followed by shot peening. This creates a "glass-hard" exterior shell to withstand bushing friction, while preserving a resilient core to absorb repetitive shock loads.
Primary Applications
The HC109 T38 D45 490 is the workhorse for:
Underground Mining: High-efficiency production drilling and long-hole blasting.
Tunnelling & Drifting: Rapid sections development of tunnel faces in civil engineering.
Bench Drilling: Maintaining high penetration rates in medium-scale quarrying.
