Rockmore International introduced its new A-series down-the-hole (DTH) hammers at Bauma.

The ROK 600A and 650A have been added to the company’s ROK range of hammers. The new 6inch-class (152mm) DTH hammers are the first models in the new A-class series.

The A hammers feature new component designs that are said to demonstrate better performance and penetration rates suited to smaller compressors.  

“We are committed to developing new DTH hammer solutions that increase productivity and reduce drilling operating costs,” said Pejman Eghdami, executive vice president of Rockmore International.

“Our new A Series line incorporates technological advancements that allow the hammers to be compatible with a wider range of compressors. This has been achieved by lowering air consumption rates and instilling higher efficiency levels.”

The piston and wear sleeve components have been redesigned to increase airflow efficiency at lower air volumes for the hammer, resulting in air consumption dropping to 26.5m³/minute at 24.1bar, while increasing penetration rates and further improving productivity and performance.

The new A Series hammers are targeted for DTH bits to drill from 155mm to 178mm in mining, construction, quarry and water-well applications. Impact power is generated from a solid piston design that is made from advanced materials then case hardened.
