Our Drum Cutters are an excellent choice for rock or concrete wall and surface profiling, trenching, frozen soil excavation, soft rock excavation in quarries, demolition and dredging. They make a quick job out of material up to 100 Mpa. Drum Cutters can be used underwater to a depth of 20 m without additional installation. Due to small grain sizes, cut rock or concrete can be used as back fill material without additional crushing. Low noise and vibration levels make our Drum Cutters suitable for use on restricted job sites and in sensitive urban areas.
