Like all T Series hammers, the ROK 550T utilises drill bits with industry-standard shank connections, without an imbedded plastic Blow Tube/Foot Valve. The new ROK 550T takes advantage of Rockmore’s patented SonicFlow technology, which optimises airflow by simplifying and streamlining the air paths to minimise back flow and turbulence, thus delivering more energy to the piston. Field testing of the SonicFlow design was determined to result in faster penetration rates and greater overall DTH hammer efficiency.
