The AQ-4 hydraulic drum cutter is designed for mid-size excavators performing rock trenching, excavation, and demolition. Its high torque output and durable transmission deliver efficient cutting performance in hard rock, producing smooth trench walls, consistent material sizing, and greater control than traditional excavation methods. The AQ-4 is also widely used for tunneling, quarrying, scaling, and reinforced concrete removal.
*Also available in a AQ-4HD, offering a reinforced cutter head for more robust cutting in hard rock. Contact us for more information
