Drum cutter attachment for excavator, also known as a rotary drum cutter, is a powerful hydraulic tool mounted on an excavator. It features a rotating drum equipped with carbide cutting picks that efficiently fragment rock, concrete, asphalt, and other hard surfaces. Boost excavation efficiency with YG’s drum cutter attachment—high precision, low vibration. The advanced drum cutter attachment is engineered to ensure smooth, controlled material removal while reducing noise and vibration. This makes it ideal for urban projects, mining operations, and environments requiring high-precision cutting.

Components of Drum Cutter Attachments
The design of a drum cutter attachment for excavator is engineered to maximize efficiency and durability. Key components include the drum body, cutting teeth, hydraulic motors, and mounting system.
- Drum Body: The drum is typically made from high-strength steel to withstand the rigors of heavy-duty cutting. Its cylindrical shape houses the cutting teeth and is connected to the excavator’s hydraulic system via a motor.
- Cutting Teeth: The teeth are strategically positioned around the drum and are often interchangeable. They come in various shapes and sizes depending on the application. Tungsten carbide tips are commonly used for their hardness and wear resistance.
- Hydraulic Motors: These motors drive the rotation of the drum. They are designed to operate under high pressure and provide the necessary torque for cutting through tough materials.
- Mounting System: The attachment is secured to the excavator’s arm using a quick-coupler system, ensuring easy installation and removal.
How Does It Work?
The core principle of the drum cutter attachment for excavator is a controlled grinding or milling action. As the hydraulic motors generate high torque, the drums rotate, and the strategically positioned picks engage with the material surface, such as rock, concrete, asphalt, or frozen soil. Unlike the high-impact force of a hydraulic breaker, the drum cutter methodically slices and mills the material, breaking it down into small, manageable pieces.
Applications of Drum Cutter Attachment for Excavator
- Tunneling and Mining: Drum cutters are extensively used in tunneling projects for excavating rock and soil. Their precision cutting minimizes overbreak and reduces the need for additional support structures. In mining operations, they assist in ore extraction and underground mine development.
- Demolition and Renovation: For demolition projects, drum cutters excel in breaking down concrete structures, removing rebar, and creating openings for doors and windows. They are particularly useful in controlled demolition scenarios where minimal collateral damage is essential.
- Road Construction and Maintenance: In road construction, drum cutters are employed for milling asphalt, creating trenches for utilities, and repairing damaged road surfaces. Their ability to cut vertically and horizontally makes them adaptable to various roadwork tasks.
- Foundation Work: When preparing foundations for buildings or bridges, drum cutters can precisely excavate footings and trenches. This ensures accurate placement of reinforcement bars and concrete, leading to stronger and more durable structures.
- Landscaping and Earthmoving: In landscaping projects, drum cutters help shape terrains, create slopes, and prepare ground for planting. Their low-vibration operation is beneficial in residential areas where noise and disturbance must be minimized.
Advantages of Drum Cutter Attachments
- Precision and Control: The rotational action of the drum allows for highly controlled cutting, enabling operators to achieve exact dimensions and angles. This precision is crucial in projects requiring tight tolerances, such as utility installations or architectural restorations.
- Reduced Vibration and Noise: Unlike impact-based tools, drum cutters operate with minimal vibration and noise. This makes them suitable for use in urban areas, near hospitals, schools, and residential neighborhoods where noise restrictions apply.
- Enhanced Safety: By reducing the need for manual labor in hazardous environments, drum cutters improve workplace safety. Operators remain protected within the excavator cabin.
- Cost-Effectiveness: While the initial investment in a drum cutter attachment may be higher than standard buckets, its efficiency and longevity result in lower long-term costs.
Maintenance and Care for Longevity
- Daily Inspections: Before each use, operators should inspect the drum cutter for signs of wear, loose bolts, or damaged components. Hydraulic hoses and fittings should be checked for leaks or abrasions.
- Lubrication: Regular lubrication of moving parts, such as bearings and pivot points, reduces friction and prevents premature wear. Use manufacturer-recommended lubricants for optimal results.
- Tooth Replacement: Cutting teeth should be monitored for wear and replaced as needed. Worn teeth reduce cutting efficiency and increase the risk of damage to the drum body.
- Storage and Transportation: When not in use, the drum cutter should be stored in a dry, secure location to prevent corrosion or damage. During transportation, ensure the attachment is securely fastened to prevent shifting or impact damage.
