Product Description
DHD35N High Pressure Submersible Drill Bit : The Preferred Equipment for Hard Rock Drilling
The preferred equipment for hard rock drilling applications requiring superior performance and reliability.
Product Overview
The DHD35N high-pressure down-the-hole hammer operates at 0.7-1.2 MPa and is engineered for drilling in hard and extremely hard rock formations. This valveless hammer design delivers fast drilling speeds and high-quality results while minimizing energy loss for excellent rock fragmentation and productivity.
Key Performance Features
- Valveless hammer design optimized for high performance under low working pressure
- Sturdy, durable construction without bottom valve for heavy-duty applications
- Maximizes energy output while reducing usage requirements
- Irreversible sleeve design for enhanced reliability
- All key internal components undergo strict heat treatment to maximize tool lifespan
Applications
The DHD35N delivers efficient rock-breaking capability and stable performance across various demanding scenarios:
- Mining Operations: Blasting hole drilling for metal and non-metal mines
- Infrastructure Projects: Anchor holes and blasting holes for tunnels, road slopes, and subway construction
- Quarrying Operations: Stone extraction drilling that quickly penetrates hard rocks
- Geological Survey: Water wells, geothermal wells, and complex strata exploration
- Foundation Construction: Pile construction, geological disaster remediation, and various rock drilling operations
