ROCKMORE ROK series DTH hammers

Optimal energy transfer is essential to DTH drilling efficiency – how much compressed air power is transferred from the piston to the bit. That is why we have revolutionized air flow management in the new ROK series high-performance DTH hammers. Our patented SonicFlow technology minimizes backflow and turbulence, enabling the piston to hit the bit harder and with greater frequency. This means increased efficiency, more power, and faster penetration. The streamlined design means fewer parts and easier maintenance. So for greater productivity, get ready to ROK.

ROCKMORE A Series Hammers

Rockmore’s A Series hammers feature component designs that demonstrate better performance and penetration rates suited to smaller compressors. The more efficient use of compressed air translates to lower air consumption, which leads to lower costs.

The piston and wear sleeve components have been re-designed to increase airflow efficiency at lower air volumes for the hammer cycle. This modification has resulted in air consumption dropping to 962 SCFM (26.5 m3/min) at 350 PSI (24.1 Bar) while increasing penetration rates and further improving productivity and performance. Thus, smaller compressors rated less than 1,000 SCFM that are common on many drill rigs, may now be utilized with the A Series DTH hammers to reach the hammers’ peak performance.

ROCKMORE T Series Hammers

Rockmore’s T Series hammer class is a breakthrough in DTH drilling technology for mining, construction, and water-well applications. In addition to its ultra high performance features, the new T series design hammers are “tubeless” as they feature standard shank connections that no longer require plastic parts commonly known as Blow Tubes or Foot Valves. The elimination of this plastic part increases reliability while not compromising drilling efficiency.
