Product Description

High air pressure DTH hammer is a kind of down-the-hole hammer, primarily used for percussive drilling in rock formations. Characterized by high air pressure and efficiency, it is ideal for areas with abundant air supply. By using compressed air to drive the piston in the cylinder, it generates high impact energy to penetrate rock efficiently.

✔

Maximum Energy Transfer: Optimized inner structure based on rock drilling theory ensures fast drilling and low air consumption.

✔

High Durability: Crafted from high-quality alloy steel with advanced processing technology for a long service life.

✔

Low Maintenance: Simple and reliable design allows for easy assembly and disassembly.

✔

Versatile Application: Suitable for mining, quarrying, water well drilling, and civil engineering.
