When contractors deal with hard rock or heavy reinforced concrete, traditional breakers often generate too much vibration and noise. They also leave rough surfaces that require additional finishing. That is why many project managers now turn to a smarter solution. YG Machinery offers our excavator rock saw for sale, a versatile attachment that transforms your excavator into a precision cutter.
This saw uses a fast‑rotating disc to slice through materials cleanly. Unlike breakers, our rock saw attachment for excavator produces straight, smooth cuts with far less dust and noise. It works well in urban construction, quarrying, road repair, and demolition. The saw fits excavators from 2 to 30 tons, giving you flexibility on various sites.
YG Machinery builds each unit with durable steel and wear‑resistant segments. Whether you cut granite, limestone, asphalt, or concrete with rebar, this equipment performs dependably. Many users finish jobs in half the time compared to breakers. In addition, lower vibration protects your excavator boom and hydraulics, reducing maintenance costs over time. We test every excavator rock saw under real conditions before delivery. When you buy from YG Machinery, you get technical support and easy spare parts access. Now let us review the specifications, working principle, operating steps, suitable materials, and efficiency benefits.
Parameter of Excavator Rock Saw Attachment
The following table lists four standard models. Each matches a specific excavator weight and offers different cutting capacities. Customized flow and pressure settings are also available.
| 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 |
From these parameters, you see that cutting depth rises with model size. The YG‑CF4 reaches 1400mm, ideal for large mining or deep foundations. For smaller trenches, the YG‑CF1 or CF2 offers a cost‑effective choice. All models run at 30 Mpa pressure, so you usually need not adjust the main relief valve. However, always verify the flow rate. Low flow reduces speed, while high flow may cause overheating.
How the Hydraulic Rock Saw for Excavator Works？
This attachment converts hydraulic power into rotation. The excavator pump sends oil to the saw motor, which turns the output shaft and disc at high speed. The disc carries segments with diamond or carbide tips. Each tip strikes the rock and chips away small pieces, creating a narrow cut slot. The cutting depth depends on how far you lower the disc.
A key advantage of this hydraulic rock saw for excavator is adjustable feed speed. You cut slowly for hard granite and faster for soft sandstone. The motor maintains constant torque, preventing stalling. A relief valve protects against pressure spikes. If the disc binds, the valve redirects oil to the tank, safeguarding the motor and excavator hydraulics.
Construction Process Using the Rock Saw Attachment for Excavator
Follow these six steps for safe and efficient operation.
- Inspect before starting. Check hydraulic oil level and cleanliness. Confirm flow and pressure match the model. Examine the disc for cracks or worn segments. Tighten all bolts.
- Mount the attachment. Align the bracket with the quick coupler or pin system. Secure with pins. Connect hoses to auxiliary ports, keeping ends clean.
- Position the saw. Lower the disc to the starting point. Keep it perpendicular for a straight line. For deep cuts, make several passes with increasing depth.
- Begin cutting. Activate the hydraulic circuit. Feed down and forward steadily. Do not force the disc, as that may cause binding. Watch for a steady stream of chips.
- Finish the cut. Lift the disc once you reach the target depth. Shut off the flow. Swing the attachment away and remove the cut block.
- Clean up. Wash the disc and body with water or air. Inspect for damage. Grease the shaft and pivot points as scheduled.
What Materials Can This Excavator Rock Saw Cut？
Our excavator rock saw for sale handles many common materials on job sites.
- Natural stones. Granite, basalt, limestone, marble, and sandstone cut well. Harder stones need slower feeding and wear segments faster, but they produce clean edges without micro‑cracks.
- Reinforced concrete. The disc cuts through both concrete and steel rebar simultaneously. This suits bridge demolition, column removal, and wall openings. The smooth surface allows direct new construction.
- Asphalt pavement. Road projects often need expansion joints or damaged section removal. The saw provides straight edges that ease patching and reduce spalling.
- Frozen ground. In cold areas, permafrost becomes extremely hard. The saw cuts through efficiently for pipeline or foundation work in winter.
- Other hard materials. Some users cut ceramic tiles, brick walls, or composites. For unique applications, consult our team for disc recommendations.
Why Rock Saw Outperforms Traditional Breaking Methods？
Contractors often ask if a saw justifies the investment over breakers. The benefits are substantial.
- Higher speed. This saw cuts continuously, while breakers hit with pauses. For medium to hard rock, the saw finishes in about one‑fifth the time, lowering hourly costs and speeding up projects.
- Better accuracy. The saw leaves a smooth, even cut. Breakers create ragged edges and internal cracks. For trenches or openings, the saw reduces grinding and patching work.
- Less vibration and noise. Breakers vibrate the boom and loosen pins and hoses over time. They also fatigue operators and disturb neighbors. The saw produces much less vibration, prolonging machine life and creating a quieter workplace. Noise levels drop significantly, helping you meet local regulations.
- Lower total cost. Though the initial price may be higher, the overall cost often proves lower. You save fuel because the saw uses less hydraulic energy per cubic meter. Saw segments typically outlast breaker chisels. The rotating mechanism has fewer parts than a breaker’s complex valve and piston, so repairs cost less.
- Environmental friendliness. With a water spray, the saw creates minimal dust. It produces no flyrock or shock waves, so you can work safely near buildings, roads, and pipelines. This is especially valuable in crowded cities or protected areas.
Each method has its place. For loose soil or gravel, a bucket or breaker works fine. But for hard rock, heavy concrete, or precision cuts, our excavator rock saw attachment clearly wins. Many customers now use saws as their primary tool and keep breakers only for secondary tasks.
