■ Product Description

The high air pressure DTH hammer is a specialized down-the-hole tool designed for high-efficiency percussive drilling in rock formations. Powered by compressed air, it drives a piston to generate intense impact energy, allowing for rapid penetration into hard rock. It is widely applied in mining, quarrying, water well drilling, and construction engineering.

Maximum Energy Transfer: Optimized inner structure based on modern rock drilling theory for faster drilling and lower air consumption.
High Durability: Crafted from premium alloy steel with advanced processing technology for a longer service life.
Simple Maintenance: Reliable internal design allows for easy assembly and disassembly, reducing downtime.
Robust Connection: Multi-head thread connecting the chuck and cylinder makes it easy to detach the bit from the hammer.
Versatile Compatibility: Fully interchangeable with standard DTH bits and drill pipes.
