DTH hammer ROK-600TRockmore International has launched the T series DTH hammer line and recently introduced the first model in this class: the ROK 600T. The new T series design hammers utilize drill bits with standard shank connections that no longer require plastic parts commonly known as blow tubes or foot valves—leading to various technical and economical advantages. The ROK 600T is a 6-in.-class model with high performance drilling characteristics rated for drilling 6.1- to 7-in. (155- to 178-mm) diameter blast holes. The bit connection for this hammer is designated by Rockmore as QL6T, which has an identical shank design to the industry standard QL60, but without the blow tube/foot valve. The new ROK 600T takes full 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.
