Rock Tools Attachments Rock Grinders range of hydraulic equipment use high torque, low impact cutting action which makes this unique attachment suitable for applications such as excavation, mining, quarrying, tunneling and trenching. Producing a byproduct that can often be used as back-fill for pipe laying. Our technology enables use in environmentally sensitive areas such as adjacent gas lines or structures where minimization of vibration is critical. With the capability for use underwater our grinders bring productivity to otherwise inaccessible and or difficult areas lowering cost and utilizing capital equipment. We have models to suit skid steers, loaders and excavators from 3 to 110 tons.
