Reliable Auger Drill Solutions
The Rotary Drum Cutter is a powerful hydraulic attachment designed for excavators, offering a precision-engineered alternative to traditional hammers and breakers. Utilizing high-torque hydraulic motors and wear-resistant picks, it excels in rock excavation, demolition, trenching, and surface profiling.
Rotary drum cutters are high-performance excavator attachments designed for precision rock excavation, demolition, and trenching. Unlike traditional hydraulic breakers, these tools utilize a high-torque grinding action to chew through hard surfaces with extremely low vibration and minimal noise. They are the go-to solution for tunneling, profiling rock walls, and precise concrete removal, especially in vibration-sensitive environments like urban centers or near hospitals. Whether it’s underwater dredging, foundation work, or cutting narrow trenches for utilities, rotary drum cutters provide a clean, controlled, and efficient alternative to blasting and hammering, ensuring projects are completed with surgical accuracy.
As a professional manufacturer of excavator attachments, we prioritize reliability and ROI. Our rotary drum cutters are tested in the most demanding environments to ensure they deliver maximum productivity with minimal downtime.

Our Rotary Drum Cutter products are available in various configurations, including transverse and axial models, each engineered for unmatched grinding power and precision. Designed to be dependable and adaptable, our cutters are provided with specialized pick arrangements that better accommodate your specific rock hardness and site requirements. Enhance your excavation proficiency and project performance today with our high-torque hydraulic solutions!
Our rotary drum cutters are designed to excavate a wide range of substrates, including soft to medium-hard rock (such as shale, limestone, and sandstone), asphalt, frozen ground, and reinforced concrete. Depending on the model and pick (teeth) configuration, they can efficiently handle materials with a compressive strength of up to 100-120 MPa.
While breakers are powerful, drum cutters offer three distinct advantages:
Low Vibration: Ideal for working near sensitive structures or underground utilities.
Precision: They produce smooth, profiled surfaces without over-excavation.
Material Quality: The milled material is small and uniform, often suitable for immediate reuse as backfill, saving you significant logistics costs.
Absolutely. Our rotary drum cutters feature advanced sealing technology and heavy-duty bearings that allow them to perform at full power in underwater environments. They are widely used for harbor dredging, cleaning submerged bridge piles, and riverbed deepening.
Transverse (Double Drum): Best for bulk excavation, tunneling, and wide trenching where high productivity is the priority.
Axial (Single Drum): Also known as a vertical cutter, it is ideal for narrow trenching, cleaning corners, precision profiling, and drilling holes where a horizontal drum cannot reach.
The picks (teeth) are wear-parts. The replacement frequency depends on the hardness and abrasiveness of the rock. We use high-grade tungsten carbide tips for maximum longevity. Our design allows for quick on-site replacement using simple tools, minimizing downtime during your shift.
Our cutters are “Plug-and-Play” compatible with most excavator brands (CAT, Komatsu, Volvo, Sany, etc.). The key is to match the excavator’s oil flow and pressure with the cutter’s requirements. We provide customized mounting brackets and hydraulic hose kits to ensure a seamless fit for your specific machine.
