Product Description

High air pressure DTH hammer is a specialized down-the-hole tool primarily used for percussive drilling in rock formations. Characterized by high air pressure and exceptional efficiency, it is ideal for areas with an abundant air supply. The hammer operates by using compressed air to drive a reciprocating piston, generating impact energy that penetrates the rock through the drill bit.

  • Maximum Energy Transfer: Designed with a special inner structure based on the latest rock drilling theory for fast speed and low air consumption.
  • Superior Materials: Adaption of high-quality alloy steel and advanced processing ensures smooth performance and long service life.
  • Easy Maintenance: Simple and reliable internal structure makes assembly and disassembly straightforward.
  • High Versatility: Multihead thread connecting chuck allows for easy departure of the bit from the hammer.
  • Broad Compatibility: Interchangeable with various DTH bits and drill pipes.
