Why Choose Our HC109 R38 D45 470 Shank Adapter?
Reinforced D45 Structural Rigidity: The 45mm body diameter provides significantly higher resistance to bending and axial fatigue compared to standard 38mm shanks. This minimized deflection ensures superior hole straightness even when drilling in highly fractured rock formations.
High-Precision R38 Threading: Our R38 threads are CNC-machined to exact industry tolerances. This ensures a tight, low-friction coupling with R38 coupling sleeves and rods, reducing thread heat build-up and preventing premature stripping.
Advanced Heat Treatment Technology: Every HC109 shank undergoes a multi-stage carburizing process followed by shot peening. This creates an ultra-hard exterior shell to withstand bushing friction, while maintaining a ductile core to absorb repetitive high-frequency shock loads.
Primary Applications
The HC109 R38 D45 470 is the professional choice for:
Underground Mining: High-efficiency production drilling and long-hole blasting.
Tunnelling & Drifting: Rapid development of tunnel faces in civil engineering projects.
Bench Drilling: Maintaining high productivity in medium-scale quarrying and infrastructure construction.
