Product Description

The High air pressure DTH hammer is an advanced down-the-hole tool primarily used for percussive drilling in rock formations. Characterized by its high air pressure operation and superior efficiency, it is the ideal choice for environments with abundant air supply. By utilizing compressed air to drive the piston's reciprocal motion within the cylinder, it generates potent impact energy delivered directly to the drill bit.

Key Advantages:

  • Maximum Energy Transfer: Inner structure designed according to the latest rock drilling theories for fast drilling and low air consumption.
  • Superior Durability: Adapted high-quality alloy steel materials and advanced processing technology ensure a long service life.
  • Simplified Maintenance: Simple and reliable inner structure makes assembly and disassembly effortless.
  • Versatile Application: Suitable for water well drilling, mining, mineral exploration, and civil engineering projects.
