Rockmore International manufactures the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining, construction and water well industries. Drill and blast engineers and water well contractors trust Rockmore’s DTH equipment because of the precision engineering and high standards of drilling efficiency built into each of our hammers and bits.
Rockmore’s ROK series 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 have revolutionized air flow management in the new ROK series high-performance DTH hammers. Our patent-pending SonicFlow technology minimizes backflow and turbulence, enabling the piston to hit the bit harder and with greater frequency. That means increased efficiency, more power, faster penetration. And the streamlined design means fewer parts and easier maintenance. So for greater productivity, get ready to ROK.
Our ROK Series DTH hammers are equipped with an adjustable choke system, which allows you to adjust the volume of air that is used to power the piston. Different size holes can be drilled into the plastic choke. A bigger hole will lower the power level and allow the excess air to help remove the cuttings and water. The choke may be drilled with a maximum hole size of 0.4" (1Omm).
