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 efficiency, it is suitable for areas with abundant air supply. The working principle involves using compressed air to drive a reciprocating piston, generating impact energy to penetrate rock formations.
Applications: Suitable for high pressure drilling rigs, water well drilling, bench drilling, mining, mineral exploration, and oil well drilling. It increases production by penetrating 15% to 30% faster than standard tools.
