DEWALT Cordless Grease Gun 20V MAX DCGG571B — 42in Hose, 10,000 PSI, Variable-Speed

The DEWALT 20V MAX Cordless Grease Gun (DCGG571B) is a battery-powered, high-volume grease gun that delivers up to 10,000 PSI through a 42" flexible hose for fast, controlled lubrication in hard-to-reach places.

Built for mechanics, fleet technicians, and equipment owners who need speed and reach, this cordless grease gun combines powerful pressure, a high-flow pump, and a variable-speed trigger to handle both stubborn fittings and high-volume lubrication tasks. The 14 oz reservoir capacity and pump output of up to 5.0 oz per minute let you move quickly through jobs, while the integrated LED and flexible hose improve visibility and access in confined or poorly lit areas.

How does this grease gun handle clogged or high-resistance fittings?

The DCGG571B uses a motor rated up to 10,000 max PSI to force grease through blocked or tight fittings that manual guns struggle with. When you need to break through hardened grease or long runs of tubing, the high-pressure output provides the extra force without manual pumping.

• 10,000 max PSI motor to clear clogged fittings
• High-volume pump delivering up to 5.0 oz/min for sustained flow
• Air-bleeder valve to ease priming after cartridge changes

What control and precision does the variable-speed trigger offer?

The variable-speed trigger lets you modulate grease flow from a trickle to full output for delicate bearings or rapid fill tasks. This control reduces over-greasing and waste while giving you tactile feedback during application.

• Trigger adjusts flow for delicate or high-volume needs
• Smoother startup to prevent sudden bursts of grease
• Better control when working on threaded or sealed fittings

Can it reach hard-to-access fittings and work in dark areas?

The included 42" flexible hose extends reach into wheel wells, chassis, and tight machine pockets where rigid guns can't reach. A bright onboard LED helps you locate fittings and see grease application in dimly lit environments.

• 42-inch flexible hose for deep or awkward access points
• Bright LED to illuminate fittings and workspaces
• Compact head profile to fit tight clearances

What features improve jobsite handling and maintenance tasks?

The grease gun's integrated foot lets you set the tool down upright on a flat surface for hands-free moments, and the air-bleeder valve simplifies priming after swapping cartridges. Built to withstand workshop use, it also carries a 3-year limited warranty for added confidence.

• Integrated foot design allows stable placement on flat surfaces
• Air-bleeder valve assists in priming after cartridge replacement
• Designed for high-flow tasks like automotive and marine lubrication

Who is this for? The DEWALT 20V MAX Cordless Grease Gun is ideal for professional mechanics, fleet maintenance crews, agricultural and construction equipment techs, and serious DIYers who need rapid, reliable lubrication across multiple machines. If you frequently contend with blocked fittings, need extended reach, or want variable speed control for different greasing tasks, this tool delivers the pressure, flow, and convenience to streamline maintenance work. Note: tool only — battery and charger sold separately.
