Horizontal / Vertical Drum Cutter Attachment for Excavator — How to Choose?
- Horizontal drum cutter: The drum axis is perpendicular to the excavator arm. It has a wide milling width, ideal for large-area flat excavation, tunnel section finishing, and road milling. Its excavator milling head usually has more teeth, delivering high cutting efficiency, especially for medium-hard rock up to 90 MPa.
- Vertical drum cutter: The drum axis is parallel to the arm, like an extended “drill”. It is suitable for narrow trenching, pile head processing, steel slag cleaning, and material mixing. With a slim body, it works in confined spaces. Some models can be customized with extended sleeves for special depth requirements.
Choose based on your working conditions: Use horizontal for tunnel profiling or large-area excavation; Use vertical for narrow trenching, slag cleaning or precise edge trimming. All our products use imported high-torque motors and bearing seals, support underwater work, and ensure stable performance in harsh environments.
Breaker Vs Drum Cutter Attachment for Excavator
- Precision & vibration: Breakers use impact force with high vibration, easily damaging surrounding rock and unable to control profile accurately. Excavator drum cutter uses rotary cutting for millimeter-level precision excavation with low disturbance, perfect for tunnels and slopes.
- Noise & dust: Breakers are extremely noisy and produce heavy dust. Excavator drum cutter runs quieter with less dust, making it more eco-friendly.
- Application: Breakers are efficient and low-cost for large boulders or very hard rock but poor at shaping. Excavator drum cutter completes excavation, finishing and loading in one pass, with higher overall efficiency.If your project demands precision, environmental protection, trenching or profiling, drum cutter attachment for excavator is the better choice.
How Do the Teeth on Excavator Milling Head Affect Efficiency?
- Material determines service life: High-quality teeth use carbide tips (tungsten steel) with wear-resistant bodies to resist heavy wear and impact. Our equipment uses high-strength alloy tools, maintaining high efficiency even in 90 MPa rock.
- Arrangement affects performance: Reasonable tooth order and angle ensure stable cutting force, reduce overload, and improve efficiency. Our years of experience let us optimize tooth layout for smoother cutting and more even wear.
- Replaceability reduces downtime: Teeth are wear parts, but well-designed holders allow quick replacement. Regular inspection and timely replacement are key to keeping milling head for excavator working efficiently.
Drum Cutter Attachment for Excavator — All-Round Attachment for Tunnels, Pits, Slopes
- Tunnel engineering: Tunnel profiling, under excavation correction, pilot tunnel excavation. Accurately controls over excavation & under excavation, reducing concrete backfill.
- Foundation pits & slopes: Mills hard soil or rock in pit support to form smooth slopes for shotcrete anchoring.
- Building demolition: Static demolition of concrete beams, columns and bridge piers with no vibration, safe near protected buildings.
- Mining & roads: Open-pit mining, road milling, frozen ground excavation, and even underwater work.
Excavator Drum Cutter Maintenance Guide
- Daily inspection: Before use, check for loose or worn teeth, cracked holders, and tight bolts.
- Lubrication: Regularly grease the gearbox and bearings as instructed, especially after underwater operation.
- Clean debris: Promptly remove rebar, wire or plastic tangled inside milling head for excavator to avoid overheating from blockage.
- Hydraulic system: Keep excavator hydraulic oil clean. Maintain flow and pressure within recommended ranges; avoid overloading.
- Storage: If unused long-term, clean the machine, apply anti-rust oil, and store in a dry place.
