Rockmore International added to its ROK series DTH hammer product line – the ROK 600A and 650A. This new A Series DTH hammer line will be officially released this month at BAUMA Munich.
The 600A and 650A are 6-in. class DTH hammers that are the first models in the newly emerging A Class hammer range from Rockmore. The A hammers feature new component designs that demonstrate better performance and penetration rates suited to smaller compressors.
