An excavator rock saw is a professional hydraulic attachment designed exclusively for excavators, engineered to cut the hardest construction materials with precision and efficiency. This excavator-mounted rock saw uses industrial-grade diamond blades to slice through granite, basalt, quartzite, reinforced concrete and large trees. It has become the standard tool for earthwork projects, rock excavation, building demolition, quarry mining and landscaping operations. Our YG CF series offers four complete models, covering all mainstream excavator tonnages from 2 to 30 tons, with saw blade diameters ranging from 0.4 meters to 2.8 meters to match every project requirement.

Working Principle of the Excavator Rock Saw
The core working principle of this hydraulic rock saw combines hydraulic transmission with advanced diamond cutting technology. It requires no external power source, drawing all energy directly from the excavator’s existing hydraulic system for simple operation and stable power output.
 First, the rock saw mounts securely to the excavator’s front arm via a rigid or quick-connect interface and connects to the hydraulic lines. This plug-and-play design ensures high efficiency and perfect compatibility with all mainstream excavator models. Second, the operator activates the hydraulic valve switch from the cab. High-pressure hydraulic oil drives the hydraulic motor to rotate at 800-1200 rpm, turning the diamond saw blade smoothly and consistently. Finally, the ultra-hard diamond cutting heads on the blade edge continuously grind and cut hard materials under extreme pressure. Meanwhile, the integrated wet cooling system sprays water onto the blade to achieve effective cooling and dust suppression. After the operation, the hydraulic oil returns to the excavator’s system and the saw blade stops rotating.


Diamond Cutting Technology: Unmatched Hardness and Durability
The secret to the exceptional performance of this excavator rock saw lies in its diamond cutting technology. Unlike traditional steel blades that dull quickly when cutting hard rock, diamond blades maintain their sharp edge for hundreds of hours of continuous use. The diamond particles are embedded in a high-strength metal matrix, creating a cutting surface that can withstand the extreme friction and pressure of cutting granite and reinforced concrete. This technology delivers clean, precise cuts without causing micro-cracks in adjacent materials. As an excavator concrete saw, it can cut through reinforced concrete with embedded steel bars cleanly in a single pass, a task that would take hours with traditional jackhammers. The precise cuts also reduce material waste and eliminate the need for secondary finishing work, saving both time and money on every project.
Optimized Hydraulic System for Maximum Efficiency
All our models operate at a uniform 30MPa working pressure, calibrated to match the hydraulic output of their corresponding excavator tonnages. This optimized design ensures maximum power transfer without overloading or damaging the excavator’s hydraulic system. The hydraulic flow ranges from 30L/min for the smallest model to 190L/min for the largest heavy-duty unit, delivering consistent torque output even under the heaviest cutting loads.
This excavator-mounted rock saw features a high-efficiency hydraulic motor that converts over 90% of hydraulic power into cutting force. This high efficiency reduces fuel consumption by up to 25% compared to generic attachments, lowering your operating costs significantly over the life of the equipment.


Water Cooling and Dust Suppression: Essential for Safe Operation
The integrated water cooling system is not just a convenience—it is an essential component that doubles the service life of your diamond blades. By spraying a continuous stream of water onto the cutting edge, it dissipates the intense heat generated by friction, preventing blade warping and breakage. Running the saw without water will destroy a new diamond blade in less than one hour.
In addition to cooling, this hydraulic rock saw also provides effective dust suppression. Construction dust is a major health hazard and environmental concern on job sites. The water spray captures dust particles at the source, keeping the air clean and ensuring compliance with strict environmental regulations. This makes the excavator concrete saw ideal for use in urban areas and residential neighborhoods where dust control is mandatory.
