Descrizione di prodotto
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
