Product Description

High air pressure DTH hammer is a specialized down-the-hole tool primarily used for percussive drilling in rock formations. Characterized by its high air pressure operation and superior efficiency, it is ideal for environments with abundant air supply. By utilizing compressed air to drive the piston in a reciprocating motion, it generates high impact energy to penetrate rock formations effectively.

  • Maximum Energy Transfer: Designed with advanced rock drilling theory to ensure fast drilling speeds and low air consumption.
  • High Durability: Constructed from high-quality alloy steel with advanced processing technology for smooth performance and long service life.
  • Easy Maintenance: Simple and reliable inner structure allows for easy assembly and disassembly, reducing downtime.
  • Versatile Connection: Features multihead thread connecting chuck for easy bit removal and interchangeability with standard drill pipes.
  • Economy & Power: Optimized for the lowest cost per foot drilled in mining, quarrying, and construction projects.
