A drum cutter attachment is an excavator-mounted hydraulic tool for milling and cutting rock, concrete and soil in controlled working conditions. YG models can be installed on 6-70 ton excavators and are designed for applications including tunnel profiling, trenching, road construction, building renovation and mining. With high-torque hydraulic motors, carbide cutting tools and multiple structural options, the attachment can handle materials with compressive strength up to 90 MPa.

6 Key Features Of The Rotary Drum Cutter
1. Poclain Hydraulic Motor
The cutter core uses a hydraulic motor manufactured by French hydraulic brand Poclain. The supplied product information highlights strong power output and low failure rates as key advantages of this configuration.
2. 1:1.3 Gearbox Reduction Ratio
The gearbox uses a 1:1.3 reduction ratio. This design increases cutting force and supports efficient milling during demanding excavation work.
3. 42 Micron And Tungsten Carbide Wear Components
The wear components use 42-micron and tungsten carbide materials. The design focuses on wear resistance for repeated milling operations.
4. 45°-85° Adjustable Spiral Arrangement
The spiral-line arrangement angle can vary between 45° and 85° according to different working conditions and rock hardness. This allows the cutting configuration to adapt to different material conditions.
5. Up To 90 MPa Rock Applications
The transverse and chain-type models are specified for hard materials with compressive strength up to 90 MPa. This makes the attachment suitable for demanding rock-milling applications where controlled cutting is required.
6. Underwater Working Capability
The transverse, vertical and chain-type configurations can be used underwater. This expands the potential application range beyond conventional dry excavation environments.
What Can A Drum Cutter Attachment Be Used For?
1. Tunnel Profiling
Tunnel construction often requires controlled removal of rock to achieve the required profile. The cutter can progressively mill material instead of relying on heavy impact, making it suitable for profile correction and surface treatment.
2. Trench Excavation
The attachment can be used for trenching in hard materials. The chain-type design is particularly notable because its full-width structure removes the central blind area found in some conventional cutter designs.
3. Road Milling And Renovation
The cutter can be used for asphalt milling and road-related excavation work. Controlled removal can help when the project requires selective milling rather than large-scale impact breaking.
4. Mining And Rock Excavation
Identifies mining as one of the major application areas. The transverse and chain-type designs can work with hard materials up to the stated 90 MPa compressive-strength level.
5. Building Demolition And Renovation
The attachment can also be used for building renovation and demolition where controlled material removal is more suitable than unrestricted impact breaking.
6. Steel Slag And Pile-Head Removal
The vertical configuration is designed for specialized applications including steel slag removal and pile-head demolition. It can also be used for material mixing and contour correction.
Which Rotary Drum Cutter Structure Should You Choose?
YG provides three structural configurations: transverse, vertical and chain-type. Each design targets different excavation, profiling and trenching requirements. The three configurations allow the attachment structure to match different working directions and project requirements.
1. Transverse Drum Cutter
The transverse configuration is designed for a broad range of applications, including trench excavation, tunnel profiling, building demolition and renovation, mining and road construction. It uses an imported high-torque motor, imported bearings and oil seals, and high-strength spur gears.
This configuration is suitable when the working direction and cutting width match conventional transverse milling requirements.
2. Vertical Drum Cutter
The vertical configuration targets more specialized applications. These include special trench excavation, steel-industry slag removal, pile-head removal, material mixing and contour profiling.
Different connection-shroud lengths can also be customized according to customer requirements and working conditions.
3. Chain-Type Drum Cutter
The chain-type configuration is designed for trench excavation, tunnel profiling, building renovation, mining and road construction.
Its full-width design removes the central gap found in conventional cutters. According to the product material, the operator does not need to swing the excavator from side to side to compensate for the central gap, and the resulting trench width does not exceed the cutter-head width.
Rock Drum Cutter Customer Application Example
Case1: Argentina Mining And Rock Work
A mining-related customer in Argentina was looking for equipment for hard-material excavation and controlled milling work. The customer needed a solution that could work with an excavator and provide more controlled material removal than conventional impact-based equipment.
The customer selected a YG milling solution after considering the attachment’s high-torque hydraulic drive, high-strength cutting tools and ability to work with hard materials. The continuous milling method allowed the operator to progressively remove material instead of relying only on repeated impact.
For this type of application, the main benefits are controlled excavation, reduced vibration and the ability to work on profiles that require greater precision. Argentina is also listed in YG’s product CRM data as a country where this product has generated a completed order.
Case2: Czech Republic Construction Project
A customer in the Czech Republic required an excavator attachment for demanding construction and material-removal work. The main challenge was finding a tool that could combine excavation capability with controlled milling in confined working areas.
The customer chose a YG solution based on the product’s high-torque hydraulic drive and cutting configuration. The milling method helped the operator progressively remove hard material while maintaining greater control over the working profile.
This type of application is particularly relevant to tunnel work, trenching and renovation projects where excessive vibration or uncontrolled breaking can create additional problems. The Czech Republic is also recorded in YG’s CRM data as a completed-order market for the product.
FAQ About Drum Cutter Attachments
The drum cutter for sale can be installed on excavators from 6 to 70 tons. The exact model should still be matched with the excavator’s hydraulic system and the intended application.
Yes. The transverse and chain-type models are specified for hard materials with compressive strength up to 90 MPa. Actual performance depends on the material and working conditions.
The two attachments use different working principles. In mudstone, sandstone and weathered-rock conditions, the cutter can work 3-5 times faster than a breaker. It also highlights precise profile milling, lower vibration and suitability for noise-sensitive areas.
Yes. The transverse, vertical and chain-type configurations can work underwater. The specific project conditions should be confirmed before selection.
The transverse model targets general trenching, tunnel profiling, road construction, demolition and mining applications. The vertical model focuses more on special trenching, steel slag removal, pile-head removal, material mixing and contour correction.
The chain-type design can be particularly relevant when a full-width trench is required. Its no-blind-area structure is designed to reduce the need for side-to-side swinging during trench milling.
