DTH Hammer for Blastholes

Rockmore International introduced the ROK 550T down the hole T Series hammer. The hammer is a 5-in.-class hammer that uses a QL5/QL50 bit shank. It drills 5.5-in. to 6-in.- diameter holes for blast-hole applications. The hammer features Rockmore’s SonicFlow technology, which optimizes airflow by simplifying and streamlining the air paths to minimize back fl ow and turbulence, thus delivering more energy to the piston, the company reported. Listed benefits include faster penetration rates and greater efficiency. T Series hammers are tubeless with bits on standard shank connections without the blow tube or foot valve.
