Rockmore International will introduce the newest addition to its T Series DTH hammer line – the ROK 550T – to the European market at Intermat in Paris, France on April 23-28. The Rockmore T Series DTH hammers are tubeless and utilize drill bits with industry standard shank connections without the imbedded plastic blow tube/ foot valve.

According to the company, Rockmore “revolutionized the drilling industry” with the launch of its first T Series DTH model, the ROK 600T, a 6-inch class model that uses a tubeless QL6/QL60 bit shank. Last year, they released the ROK 60T-360T hammers that utilize the IR 360 bit shank without the blow tube/ foot valve.

Now, Rockmore extends the T Series with the ROK 550T, a 5-inch class hammer model that uses the industry standard QL5/QL50 bit shank, but with the blow tube/ foot valve removed. With high performance drilling characteristics rated for drilling 5.5- to 6.0-inch diameter holes, the ROK 550T is suitable for blast-hole applications in the mining and construction sectors and for deep hole drilling in the water well and geothermal sectors.  

As with all Rockmore DTH hammers, the ROK 550T takes advantage of Rockmore’s patented SonicFlow technology, which optimizes airflow by simplifying and streamlining the air paths to minimize back flow and turbulence, thus delivering more energy to the piston. Field testing of the SonicFlow design was determined to result in faster penetration rates and greater overall DTH hammer efficiency.

Rockmore International is a global manufacturer of rock drilling tools, serving the mining, construction, and water-well sectors for more than 65 years.
