Product Description

The high air pressure DTH hammer is a specialized down-the-hole tool designed for high-efficiency percussive drilling in rock formations. By utilizing compressed air to drive the piston in a reciprocating motion, it generates powerful impact energy directly to the drill bit. This tool is ideal for mining, quarrying, water well drilling, and civil engineering construction.

Key Advantages:

Maximum energy delivery for faster drilling speed

Low air consumption with optimized inner structure

High-quality alloy steel for extended service life

Simplified design for easy maintenance and assembly

Interchangeable with standard bits and drill pipes

Foot Valve not required in the bit design
