Product Description
High air pressure DTH hammer is a kind of down-the-hole hammer, mainly used for percussive drilling in rock formation. Characterized by high air pressure and high efficiency, it is ideal for areas with abundant air supply. By using compressed air to drive the piston, it generates impact energy to penetrate rock formations effectively.
  • Maximum energy delivery to drilling bits for faster penetration.
  • Low air consumption due to specialized inner structure.
  • High-quality alloy steel materials for extended service life.
  • Simple design ensures low problem rates and easy maintenance.
  • Interchangeable with standard DTH bits and drill pipes.
