DOA DC22 Hydraulic Cut-Off Saw – 20" Professional Hydraulic Concrete & Asphalt Saw

The DOA DC22 Hydraulic Disc Saw is a professional-grade 20-inch hydraulic cut-off saw engineered for contractors, utility crews, municipalities, underwater divers, and industrial maintenance professionals who demand exceptional cutting power, durability, and reliability. Designed and manufactured in Italy by DOA Hydraulic Tools, the DC22 delivers outstanding performance when cutting reinforced concrete, asphalt, masonry, steel-reinforced structures, stone, and a wide variety of construction materials. Its rugged hydraulic design eliminates the limitations of gas-powered and electric cut-off saws while providing safer operation in demanding environments.

Heavy-Duty Hydraulic Performance

Powered by DOA's exclusive high-performance hydraulic motor, the DC22 maintains exceptional torque even under heavy cutting loads. Unlike traditional belt-driven saws, the DC22 features a direct-drive transmission, eliminating belts that can stretch, wear, or fail. This results in greater reliability, lower maintenance requirements, improved power transfer, and longer service life in the harshest working conditions.

Operating on a hydraulic flow of 40 L/min at a working pressure of 140–180 bar, the DC22 is optimized for professional hydraulic power units and delivers smooth, consistent cutting performance throughout the workday.

20-Inch Blade Capacity for Maximum Cutting Depth

The DOA DC22 accepts cutting discs up to 500 mm (20 inches) in diameter, providing an impressive maximum cutting depth of 202 mm (approximately 8 inches). This makes the saw ideal for:

• Concrete slab cutting
• Asphalt pavement repairs
• Bridge and highway maintenance
• Utility trench work
• Pipe installation projects
• Demolition work
• Marine and dock construction
• Industrial maintenance
• Rescue operations
• Mining and energy infrastructure

The standard 25.4 mm (1-inch) arbor accommodates a wide variety of professional diamond and abrasive cutting blades for virtually any cutting application.

Integrated Water Cooling System

Unlike many hydraulic cut-off saws that rely on exposed external water hoses, the DC22 incorporates an innovative center-fed internal water delivery system. Water is supplied directly through the center of the blade, providing efficient cooling exactly where it is needed while eliminating vulnerable external hoses that can become damaged on the jobsite.

A convenient onboard water shutoff lever allows operators to instantly control water flow, reducing water usage while extending blade life and minimizing airborne silica dust during concrete cutting.

Built for Continuous Professional Use

Every moving component inside the DOA DC22 is continuously lubricated, helping reduce wear while increasing reliability during extended operation. The robust hydraulic motor is designed by DOA for continuous-duty service and is capable of extremely high rotational performance while maintaining excellent efficiency and durability.

Hydraulic operation also eliminates many common issues associated with gasoline-powered cut-off saws, including:

• No engine maintenance
• No carburetor problems
• No spark plugs
• No fuel mixing
• No exhaust emissions
• Lower operating noise
• Reduced vibration
• No electrical shock hazards

Convertible Asphalt Saw

For added versatility, the DC22 can quickly be mounted onto the optional DOA SC40 Saw Cart, transforming the handheld saw into a highly productive walk-behind asphalt cutter. This provides operators with improved cutting accuracy, consistent cutting depth, reduced fatigue, and greater productivity on road maintenance and pavement repair projects.

Underwater Cutting Capability

One of the features that distinguishes the DOA DC22 from conventional cut-off saws is its availability in an underwater configuration. Hydraulic power allows the saw to safely operate in submerged environments where electric tools cannot be used and gasoline engines are impractical. This makes the DC22 an outstanding solution for:

• Commercial diving operations
• Marine construction
• Bridge inspections and repairs
• Port maintenance
• Offshore energy projects
• Dam maintenance
• Salvage operations
