Product Description

The high air pressure DTH (Down-The-Hole) hammer is a specialized percussive drilling tool designed for rock formation. Driven by compressed air, it utilizes a reciprocating piston to generate high-impact energy, ensuring efficient drilling in mining, quarrying, and construction projects. Designed for perfect unison with drill bits, it provides high penetration rates and extended service life at low operational costs.

  • Maximum Energy Transfer: Optimized inner structure based on modern rock drilling theory for faster speeds and lower air consumption.
  • Superior Durability: Crafted from high-quality alloy steel with advanced processing technology for smooth performance.
  • Easy Maintenance: Simplified internal structure allows for reliable and quick assembly/disassembly.
  • High Compatibility: Multi-head thread connecting chuck makes it easy to depart bits; interchangeable with standard DTH bits and drill pipes.
  • Versatile Application: Suitable for water well drilling, bench drilling, mineral exploration, and oil well applications.
