The ROK 500 and 500Q are the latest additions to the ROK Series DTH Hammer product line. These new 5-in.-diameter class hammers take full advantage of Rockmore International’s patented SonicFlow technology. The ROK 500 hammer is rated for use with large compressors: 24.1 bar at 28.6 cu. m./min. The ROK 500Q hammer is designed for smaller compressors: 24.1 bar at 23.4 cu. m./min. Both hammers optimize airflow by simplifying and streamlining the air path to minimize backflow and turbulence, thus delivering more energy to the piston. Optional back reaming buttons on the Top Sub offer increased drill life. Field testing of the SonicFlow design was found to result in faster penetration rates and greater overall efficiency, the company says. Exclusive lead threads on the Top Sub and Driver Sub ensure easy coupling and uncoupling of the hammer.
