DTH hammer

Durpoten DP and DPA Series High-Performance DTH Hammers
Optimal energy transfer is essential to DTH drilling efficiency-how much compressed air power is delivered to the bit. That's why we've revolutionized airflow management in the DP series high performance DTH hammers. Our patent pending Kaolatube technology(DPA series) minimizes back flow and turbulence, enabling the piston to hit the bit harder and with greater frequency. That means increased efficiency, more power, and faster penetration.
