This is commonly used for: wet cutting concrete or masonry with cut-off saws; supplying flush water to diamond concrete chainsaws; cooling core drill bits on interior floors; and controlling silica dust on remote utility trenches. It is ideal when your jobsite has no accessible outdoor spigot or when dragging hundreds of feet of hose is impractical. For high-volume, multi-day road saw cutting with heavy water demands, a continuous municipal hookup or large towable water trailer is a better choice.

The integrated 12V pump runs directly on a DeWalt 20V power tool battery for cordless mobility anywhere on the job. It also includes an auxiliary 12V power cord with alligator clips so you can run the pump off a vehicle or equipment battery if your cordless battery runs out. Be sure to verify your battery is fully charged before heading to remote sites.

Run time depends on the specific cutting tool and flow rate setting, but handheld cut-off saws and core drills typically use 0.5 to 1.5 gallons per minute, giving you roughly 10 to 30 minutes of active cutting per fill. Diamond concrete chainsaws require higher flush rates to clear slurry, so plan to keep extra water jugs nearby for quick refills on larger jobs.

The unit connects to standard concrete cut-off saws, diamond chainsaws, core drill rigs, and masonry saws equipped with standard garden hose thread (GHT) or quick-disconnect fittings. The electric pump provides consistent, pressurized flow directly to the tool's spray nozzles without the constant manual pumping required by hand sprayers.

The wheeled cart fits easily into pickup beds, cargo vans, or SUV cargo areas. You should always transport the tank completely empty, as 15 gallons of water adds approximately 125 pounds of shifting liquid weight that can cause spills and make lifting hazardous. Fill the tank once you arrive on site using an available water source or transport containers.

Do not allow the pump to run dry once the water tank is empty, as continuous dry running will overheat and damage the internal pump diaphragm. Always switch the pump off when pausing work, and only fill the tank with clean, grit-free water to prevent clogging the intake screen and tool cooling ports.
