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. It is suitable for use in areas with abundant air supply. The working principle of the high air pressure DTH hammer is to use compressed air to drive the piston to reciprocate in the cylinder, thereby generating impact energy to impact the drill bit and drill into the rock formation.

Deliver maximum energy to drilling bit, fast drilling speed and low air consumption.
Smooth performance and long service life due to high quality alloy steel materials.
Low problem rate and easy maintenance due to simple, reliable inner structure.
Easy to depart bit from hammer due to multihead thread connecting chuck.
Interchangeable with DTH bit and drill pipe.
Penetrate 15% to 30% faster than conventional hammers.
