Product Description

High air pressure DTH hammer is a specialized down-the-hole tool designed for percussive drilling in rock formations. Characterized by its high air pressure and superior efficiency, it is the ideal choice for areas with abundant air supply. By using compressed air to drive the piston reciprocation, it generates powerful impact energy to penetrate rock formations rapidly.

⭐ Key Advantages

Maximum Energy Transfer: Inner structure designed according to the latest rock drilling theory for fast speed and low air consumption.
Premium Materials: Adaptation of high-quality alloy steel and advanced processing ensures smooth performance.
Easy Maintenance: Simple and reliable internal structure makes assembly and disassembly effortless.
High Compatibility: Multi-head thread connecting chuck allows for easy departure of bit from hammer; interchangeable with DTH bits and drill pipes.
