Maximize your heavy-duty drilling efficiency with the HC109RP T38 D45 670 shank adapter. Specifically engineered for HC109RP series hydraulic drifters, this 670mm extra-long 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 bending and fatigue in complex mining and tunneling environments.
Product Specifications
Drill Compatibility: Fully optimized for HC109RP hydraulic drills
Core Benefit: Ideal for deep-hole drilling and high-stress rock formations
Core Advantages of the HC109RP T38 D45 670
Robust T38 Thread System: The T38 thread provides an expanded surface area to distribute high-torque rotational forces. This significantly minimizes thread wear and prevents "cold welding" or stripping when drilling deep holes or encountering jamming-prone fractured ground.
Reinforced D45 Structural Stability: With an extended length of 670mm, structural rigidity is critical. The 45mm diameter provides extreme resistance against bending and shearing stresses, ensuring superior hole straightness even under high feed pressures.
Advanced Surface Engineering: Every HC109RP shank undergoes strict full-body carburizing followed by high-intensity shot peening. This introduces beneficial compressive stresses, creating an ultra-hard skin that resists guide-bushing abrasion while maintaining a ductile core to absorb repetitive impacts.
Primary Applications
The HC109RP T38 D45 670 is the workhorse for:
Underground Production Mining: Long-hole stoping and specialized drilling.
Complex Tunneling & Drifting: Umbrella arch configurations and forepoling support.
Deep Hole Reinforcement: High-accuracy drilling for structural rock bolts.
