Rockmore International introduces the second model in the new T-Series DTH hammer line — the ROK 550T. The new T-Series design hammers utilize drill bits with standard shank connections without the plastic blow tubes/foot valves. The ROK 550T is a 5-inch class model and a “tubeless” hammer that accepts the industry standard bit shank model QL50, but with the blow tube/foot valve removed.
