New Five-Inch Class Tubeless DTH Hammer Global manufacturer of rock drilling tools, Rockmore International has been serving the mining, construction, and water well sectors for more than 65 years. Rockmore revolutionized the drilling industry with the launch of its first T Series DTH (down-the-hole) model, the ROK 600T, a six-inch class model which uses a tubeless QL6/QL60 bit shank. Last year, the company released the ROK 60T-360T hammers utilizing the IR 360 bit shank without the blow tube/foot valve. Now, Rockmore extended the T Series to the new ROK 550T, a five-inch class tubeless hammer model which uses the industry standard QL5/QL50 bit shank, but with the blow tube/foot valve removed. With high-performance drilling charac- teristics rated for drilling 5.5-inch to 6.0- inch-diameter holes, the ROK 550T is suitable for blasthole 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 new ROK 550T takes advantage of Rockmore’s patented SonicFlow tech- nology, which optimizes airflow by sim- plifying and streamlining the air paths to minimize backflow and turbulence, thus delivering more energy to the piston. Field testing of the SonicFlow design was determined to result in faster pen- etration rates and greater overall DTH hammer efficiency. For a link to this website, visit: worldwidedrillingresource.com
