Product Description

High air pressure DTH hammer is a kind of down-the-hole hammer. It is mainly used for percussive drilling in rock formation. It is characterized by high air pressure and high efficiency, suitable for use in areas with abundant air supply. The working principle involves using compressed air to drive the piston to reciprocate in the cylinder, generating impact energy to impact the drill bit into the rock formation.

Core Advantages:

Maximum energy delivery to drilling bit for fast penetration.
High quality alloy steel materials and advanced processing technology.
Simple and reliable inner structure for easy maintenance.
Multihead thread connecting for easy bit departure.
Fully interchangeable with DTH bit and drill pipe.

Applications: Bench drilling, Water well drilling, Mining/Mineral Exploration, Civil Engineering, and Oil well drilling.
