The Henglong R32 42mm threaded cross drill bit is engineered for high-performance rock drilling in mining, quarrying, and construction applications. This robust tool delivers reliable performance even in the most challenging geological conditions.
Key Advantages
Optimized Cross-Cutting Design
Features a symmetrical cross-shaped carbide insert layout with four wear-resistant cutting edges that evenly distribute drilling pressure. This eliminates stress concentrations, reduces deflection, and ensures clean, consistent drilling. The 42mm diameter provides optimal balance between drilling speed and borehole stability.
R32 Threaded Connection
Standard R32 threaded connector ensures tight, vibration-resistant connection with compatible drill rods. Precision-machined threads minimize power loss during torque transmission, prevent accidental disconnection, and support quick, tool-free installation and removal.
High-Strength Material Construction
Forged from premium alloy steel and subjected to quenching and tempering heat treatment for enhanced impact toughness and durability.
Application Scenarios
- Hard Rock Mining: Ideal for blast hole drilling in gold, copper, and iron mines
- Quarrying Operations: Delivers stable performance and maintains borehole straightness in hard rock quarrying
- Civil Engineering: Suitable for slope anchoring, foundation piling, and tunnel excavation projects requiring reliable, low-maintenance drilling tools
Quality Assurance
Our products undergo rigorous quality control throughout production, from raw material testing to final dynamic balancing calibration. Each drill bit is tested for torque resistance and impact durability before leaving the factory, ensuring compliance with ISO 17144 standards for rock drilling tools.
