About these itemsPrecision Wet Cutting with Water AttachmentEach electric concrete saw includes a built-in wet-cutting system that sprays water directly onto the blade to reduce airborne dust and debris during operation. This minimizes health hazards and improves cutting precision while eliminating the need for manual watering. Whether working on stone, brick, or reinforced concrete, you get a cleaner and safer cut.Powerful Pure Copper MotorsRanging from 1800W to 3200W, these concrete cutters are equipped with pure copper motors designed for high-efficiency cutting. Featuring no burn-out design, speeds vary between 3600â5800 RPM, enabling smooth, fast, and stable slotting. The motors are heat-resistant and built for long-term reliability in demanding construction environments.Optimized Safety and Control FeaturesSafety comes standard with double-switch controls that prevent accidental startups, slow-start functionality for smoother operation, and built-in GFCI to reduce electrical hazards. Overload protection further extends product lifespan while offering peace of mind during intensive tasks.Wheeled Base with Ergonomic HandleEvery saw includes a wheeled base that doubles as a precision positioning guide, enabling accurate, low-effort cutting over long sessions. The large D-shaped handles are ergonomically designed for operator comfort, even during extended use. These mobility-enhancing features make them ideal for both DIY and professional jobsites.Variable Cutting Depths for Versatile UseModels offer cutting depths from 2.5" up to 6", with blade diameters ranging from 7" to 16". Suitable for different power sources (15A to 32A), they are ideal for cutting concrete, masonry, pavings, bricks, and more. Whether for shallow grooves or deeper cuts, these saws provide the flexibility you need on the job.Key DifferencesDC180 offers a 7" blade and 2.5" cutting depth with 2000W power and 5400 RPM speed. It is the lightest model at 19 lbs, ideal for lighter-duty tasks and quick cuts in tight spaces.DC235 uses a 9" blade, 3.5" cutting depth, 1800W motor, and runs at 5800 RPM. It balances cutting depth and speed for moderate-duty jobs.DC305 increases the blade size to 12" with a 4.5" cutting depth and a lower 5300 RPM speed, weighing 28.7 lbs and offering enhanced stability for deeper cuts.DC355 features a 14" blade and cuts up to 5" deep, powered by a 2600W motor at 4600 RPM. It offers a powerful balance between depth and manageability.DC425 is the largest and most powerful option, with a 16" blade and 6" cutting depth, supported by a 3200W motor running at 3600 RPM. Best suited for heavy-duty and commercial concrete work.SpecificationsModel: DC180Blade Diameter: 7"Cutting Depth: 2.5"Power: 2000WSpeed: 5400 RPMWeight: 19 lbs (8.6 kg)Voltage: AC 110V / 60HzDimensions: 25.98 x 8.66 x 12.80"Model: DC235Blade Diameter: 9"Cutting Depth: 3.5"Power: 1800WSpeed: 5800 RPMWeight: 18.3 lbs (8.3 kg)Voltage: AC 120V / 60HzDimensions: 28 x 21 x 13"Model: DC305Blade Diameter: 12"Cutting Depth: 4.5"Power: 1800WSpeed: 5300 RPMWeight: 28.7 lbs (13 kg)Voltage: AC 120V / 60HzDimensions: 28 x 9 x 13"Model: DC355Blade Diameter: 14"Cutting Depth: 5"Power: 2600WSpeed: 4600 RPMWeight: 34.8 lbs (15.8 kg)Voltage: AC 120V / 60HzDimensions: 28 x 9 x 13"Model: DC425Blade Diameter: 16"Cutting Depth: 6"Power: 3200WSpeed: 3600 RPMWeight: 37.5 lbs (17 kg)Voltage: AC 120V / 60HzDimensions: 32 x 9 x 19"Package ContentsDC1801 x Electric Saw1 x 7" Blade1 x Wrench1 x Water Pump1 x Water Hose2 x Hose Clamps1 x User ManualDC2351 x 9" Cutting Blade1 x Spanner1 x Water Pump1 x Ï8*5000 Water LineDC3051 x 12" Cutting Blade1 x Spanner1 x Water Pump1 x Ï8*5000 Water LineDC3551 x 14" Cutting Blade1 x Spanner1 x Water Pump1 x Ï8*5000 Water LineDC4251 x 16" Cutting Blade2 x Carbon Brushes1 x Spanner1 x Water Pump1 x Ï8*5000 Water Line1800W12in4.5in
