ROK 550T to make European debut

PRESS RELEASE: The Rockmore T Series DTH hammers are ‘tubeless’ and utilise drill bits with industry standard shank connections without the imbedded plastic blow tube/foot valve.

In 2017, Rockmore released the ROK 60T-360T hammers that utilise the IR 360 bit shank without the blow tube/foot valve.

Now, Rockmore has extended the T series to the new ROK 550T, a 5in (127mm) class hammer model which uses the industry standard QL5/QL50 bit shank, but with the blow tube/foot valve removed. With high performance drilling characteristics rated for drilling 5.5-6in (140-152mm) diameter holes, the ROK 550T is suitable for blasthole applications in the mining and construction sectors and for deep hole drilling in the water-well and geothermal sectors.

As with all Rockmore DTH hammers, the new ROK 550T uses Rockmore’s 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.
