YG rotary drum cutter for excavator is a hydraulic attachment mounted on the front boom of an excavator, specifically designed for excavation, shaping, and trenching of rock, concrete, and frozen soil. This drum cutter boasts high efficiency, fast rotation speed, quiet operation, and minimal dust. It features high precision, low noise, low vibration, simple structure, ease of use, and the ability to backfill waste materials. It is ideal for construction environments with limited noise or vibration and can replace traditional hydraulic breakers or blasting methods.
As a direct manufacturer, we build these tools to handle tough jobs easily. When your breaker cannot do the job neatly, this attachment cuts through hard ground with smooth movements. It helps you finish your project on time without disturbing nearby areas.

An Excavator Milling Head Main Applications
An excavator milling head is a multi-purpose tool. It works well in many difficult working conditions. Our global customers use this equipment for five main tasks.
1.Rock and Concrete Excavation
It cuts through rock layers and thick concrete walls smoothly. Unlike big crushers, it leaves clean edges and does not crack the surrounding structure.
2.Trenching
When you need to lay pipes or cables, this tool digs narrow trenches quickly. It controls the width and depth perfectly, which saves you a lot of extra digging work.
3.Profiling
It is excellent for smoothing out tunnel walls or leveling uneven rock surfaces. It shaves off the exact amount of material you want.
4.Demolition
It breaks down old buildings, bridges, and foundations safely. It creates very little dust and noise, so you can work during the night in busy cities.
5.Underwater Applications
You can use this machine under water to clean riverbeds or deepen canals. The sealed body keeps water out of the hydraulic system.

Key Benefits of Using A Drum Cutter Machine
Using a drum cutter machine brings many good things to your construction site. It changes the way you cut rock and concrete. Here are the main benefits you will get:
- Low vibration: It is very safe to use in sensitive urban or industrial areas. It will not shake or damage the buildings nearby.
- Low noise: When noise is a big problem and other attachment tools are not allowed, these machines are your best option. You can work in school or hospital zones without trouble.
- High production rates: These cutters are ideal for soft rock excavation and demolition. They perform much better than other attachment tools in this field.
- Small grain size: The cut material has a small grain size. You can use it for backfill directly. You do not need to buy extra materials to fill the holes.
- High return on investment: You save money because of accurate material removal. You do not need to transport or crush broken material. High productivity allows contractors to make more money fast.

Rotary Drum Cutter Vs. Traditional Hydraulic Breaker
When choosing excavation tools, many contractors compare a rotary drum cutter with a traditional hydraulic breaker. While breakers smash rock with heavy impacts, a drum cutter shaves material away continuously. Here is why our milling head is often the better choice for your job site:
- Precision and Shape: A hydraulic breaker cracks rock randomly, leaving rough and uneven surfaces. A drum cutter machine cuts exact lines and smooth walls. This is perfect for tunnel profiling and narrow trenching.
- Vibration and Safety: Breakers create huge shockwaves. These vibrations can crack the foundations of nearby houses or historical buildings. Our cutter runs smoothly with low vibration, making it safe for indoor or urban demolition.
- Noise Levels: Breakers make a very loud, sharp noise that can disturb whole neighborhoods. Our hydraulic rock drum cutters operate with low noise, allowing you to work at night or in quiet zones.
- Material Recycling: Breakers leave behind giant, useless chunks of concrete or rock that you must haul away and crush. The drum cutter produces small grain sizes immediately. You can use this waste material for backfill right away, saving transport costs.

How to Choose the Right Rotary Drum Cutter for Your Excavator
Selecting the correct rotary drum cutter ensures your project runs smoothly and protects your excavator from damage. Do not just pick the biggest size. You need to follow these five easy rules:
1.Carrier Compatibility
You must match the cutter size and hydraulic power with your excavator’s weight class. For example, a 10–15 ton excavator fits our 45 Kw model perfectly, while a 20–24 ton machine needs the 65 Kw model.
2.Hydraulic Flow and Pressure
Your excavator must provide enough oil flow and pressure. If the flow is too low, the drum will turn too slowly. If it is too high, it might hurt the tool.
3.Material Type
Select the drum type and cutting picks according to rock hardness or material type. Harder rock needs stronger, sharper picks.
4.Environmental Requirements
Think about your job site. Low-noise and water-resistant options are ideal for urban neighborhoods or underwater river work.
5.Service and Support
Always choose a manufacturer brand with reliable after-sales service and spare parts availability. YG provides fast shipping for replacement picks and drums so your work never stops.
