Product Description

The high air pressure DTH (Down-The-Hole) hammer is an advanced percussive drilling tool designed for rock formation. Driven by compressed air, the piston reciprocates in the cylinder to generate high impact energy, making it ideal for mining, quarrying, and construction.

  • Maximum Energy Transfer: Special inner structure based on modern rock drilling theory ensures fast speed and low air consumption.
  • High Durability: Adapted high-quality alloy steel materials and advanced processing technology.
  • Easy Maintenance: Simple and reliable inner structure allows for easy assembly and disassembly.
  • Versatile Connection: Multi-head thread connecting chuck and cylinder makes bit removal effortless.
  • Compatibility: Fully interchangeable with standard DTH bits and drill pipes.
