When you face hard rock or concrete, an excavator rock saw is the ideal attachment. YG Machinery offers reliable rock saws for carriers from 2 to 30 tons. These tools turn your excavator into a powerful rock cutter. You get smooth, straight cuts in the toughest materials. Our saws use advanced hydraulic drive technology. They help you finish jobs faster while reducing noise and ground vibration. Read on to see the models and how they can improve your projects.
YG Excavator Rock Saw Technical Parameters
The table below lists the four main models. Pick the right rock saw based on your machine weight and the depth you need.
| Model | YG-CF1 | YG-CF2 | YG-CF3 | YG-CF4 |
| Suitable for excavators | 2~4T | 6~9T | 10~18T | 20~30T |
| Saw Disc Diameter | 0.4~0.8M | 1.2~1.6M | 1.8~2.2M | 2~2.8M |
| Cutting width | 5mm | 9mm | 14mm | 20mm |
| Cutting depth | ≤400mm | ≤800mm | ≤1100mm | ≤1400mm |
| Pressure | 30Mpa | 30Mpa | 30Mpa | 30Mpa |
| Flow | 30L/min | 80L/min | 120L/min | 190L/min |
All models work at a steady 30 MPa pressure. Flow requirements increase with size. This design ensures the best cutting force for each machine class.


What Is an Excavator Rock Saw?
An excavator rock saw is a hydraulic attachment that cuts rock, concrete, and similar hard materials. People also call it an excavator rock cutter or an excavator hydraulic rock saw. A circular saw disc rotates at high speed. The operator presses it against the work surface. It slices through material in a controlled, accurate way. The result is a clean trench or profile with very little overbreak. You avoid the micro-fractures that impact methods often cause. That makes it safe for sensitive sites, such as urban foundations and pipeline corridors.
Main Components and How an Excavator Hydraulic Rock Saw Works
An excavator hydraulic rock saw has a simple but strong structure. Its main parts are listed here.
- Saw disc: A high-strength alloy blade with wear-resistant teeth. Disc diameter and width change with the model.
- Hydraulic motor: It converts the excavator’s oil flow into smooth mechanical rotation.
- Gear transmission box: Sealed and lubricated, it transfers torque from the motor to the saw disc.
- Mounting bracket: A heavy plate and pin system that connects the tool to the excavator arm quickly.
- Protective guard: It covers the upper half of the disc for safety and dust control.
Now here is the working principle. High-pressure oil from the excavator flows into the hydraulic motor. The motor spins the gearbox and the saw disc. The operator lowers the rotating disc onto the rock. The teeth cut into the surface with steady pressure. The tool slices down to the needed depth along the planned line. A spray nozzle can add water to cool the blade and suppress dust. This whole process gives a neat cut with low vibration and minimal waste.
Excavator Mounted Rock Saw Applications
You can use an excavator mounted rock saw in many different jobs.
- Trenching for pipelines and cables. It creates a neat, narrow trench in hard soil and rock.
- Foundation and basement excavation. It cuts perimeter walls and footings without damaging surrounding areas.
- Quarrying and mining. It makes clean cuts for stone blocks and removes overburden precisely.
- Road and bridge work. It cuts through asphalt, curbs, and reinforced concrete safely.
- Tunnel profile trimming. It shapes tunnel walls and floors with high accuracy.
- Underwater cutting in shallow areas. With proper seals, the saw operates in water to cut rock or concrete.
In each case, the attachment lowers job time and material waste. It also reduces the need for secondary breaking or manual trimming.


YG Excavator Rock Cutter Advantages
Why choose a YG excavator rock cutter? Several features make our tools stand out.
- Wide compatibility: We offer four models that cover excavators from 2 to 30 tons. The mounting bracket fits common coupler systems.
- Deep cutting ability: Cutting depth reaches 1400 mm with the YG-CF4. This suits most trenching and rock removal work.
- Durable saw disc: Our alloy disc uses high-grade wear steel. It keeps its edge longer and cuts through hard materials reliably.
- Efficient hydraulic system: The motor design uses flow efficiently. Even at 30 MPa, you get strong cutting torque without overheating.
- Easy maintenance: Sealed bearings and a simple gearbox reduce daily service. You can replace the saw disc quickly on site.
- Smooth operation: Low vibration and controlled cutting protect your excavator and the operator. The saw also produces less noise than breakers.
- Trusted quality: Every tool undergoes strict factory testing. We provide a one-year warranty and responsive after-sales support.
Excavator Rock Saw FAQ
Here are common questions about our excavator rock saw.
Answer: Our four models cover carriers from 2 to 30 tons. Check the parameter table to match your machine. For a 5-ton excavator, YG-CF2 fits well. Contact us with your machine model for a precise recommendation.
Answer: Maximum cutting depth ranges from 400 mm to 1400 mm. YG-CF1 reaches 400 mm, while the largest YG-CF4 reaches 1400 mm. Choose the model based on the trench depth your project requires.
Answer: Yes, the saw disc works on many materials, including hard rock, reinforced concrete, and asphalt. For heavy rebar, we suggest a slower feed and a disc with reinforced segments. The same attachment handles them all with proper use.
Answer: Yes, the disc wears over time and is designed for fast replacement. You can buy original discs from YG. We keep stock for all models, and the change takes only a few minutes with basic tools.
Answer: Check hydraulic oil and filter quality regularly. Grease the pivot points daily. Inspect the disc for wear before each shift. If you cut dry, use a lower feed rate. Store the tool in a dry place when not in use.
