PRODUCT DESCRIPTION
High air pressure DTH hammer is a premier down-the-hole tool primarily used for percussive drilling in rock formations. Characterized by high air pressure and superior efficiency, it utilizes compressed air to drive a reciprocating piston in the cylinder, generating impact energy to penetrate rock formations rapidly.
Key Advantages:
  • Maximum energy delivery to the drilling bit for faster penetration.
  • Low air consumption due to optimized internal structure based on advanced rock drilling theory.
  • Smooth performance and long service life using high-quality alloy steel and advanced processing.
  • Simple design ensures a low problem rate and easy maintenance.
  • Easy bit detachment via multi-head thread connecting chuck and cylinder.
This hammer is widely applicable across mining, quarrying, construction, water well drilling, bench drilling, and civil engineering projects. It delivers record-breaking penetration at the lowest cost per foot drilled.
