Imagine the worst to produce the best. Our experience in breaking Blue Granite, scientifically proven to be one of the hardest rocks in the world, has created this philosophy. In order to break one of the hardest rocks in the world, a hammer had to be produced which was even stronger. That's why DNB Rock Breakers are built with the hardest conditions in mind. In all environmental conditions and in high production, DNB Breakers provide continuous breaking power, regardless of material.

The best raw materials are used to build each part of the hammer because we know that replacing tools and repairing equipment is not only an inconvenience, it also means time away from work and profits. Powerful impact energy and a variable impact rate, increase breaking frequency while decreasing time needed to get the job done.

DNB ll's series designed to meet tight noise regulations. These units are engineered to meet the conditions for silent demolition, such as for built up and residential areas, and enclosed commercial areas.
