DEWALT 20V MAX Cordless Grease Gun Kit DCGG571M1 — 4.0Ah Battery, 42" Hose, 10,000 PSI, LED Light

Built for technicians, mechanics, boat owners and anyone who services bearings or pivot points, this battery grease gun combines strong pumping power with portability. The kit includes a 20V MAX XR 4.0Ah lithium-ion battery, fast charger, shoulder strap and a durable kit box so you can move between jobs without relying on air lines or manual leverage. Its 14 oz grease capacity and high-flow pump are optimized for frequent greasing tasks where speed and control matter.

How does the DEWALT grease gun handle clogged or tough fittings?

The DCGG571M1 features a motor engineered to produce up to 10,000 max PSI, allowing it to break through blocked or partially clogged fittings that would stall lower-powered units. A heavy-duty pump combined with an air-bleeder valve and pump filter screen helps maintain consistent flow and prevents contaminants from jamming the mechanism.

• 10,000 max PSI motor force for stubborn fittings
• Pump filter screen to stop dirt entering the pump
• Air-bleeder valve for faster priming after cartridge changes
• Up to 5.0 oz/min high-flow delivery for quicker service

What features help me reach and see hard-to-access grease points?

The grease gun comes with a 42-inch flexible hose that extends to recessed or awkward fittings, while the integrated LED light illuminates dark service areas. An integrated no-mar foot lets you set the tool down on surfaces without scratching components, and the shoulder strap reduces fatigue when moving between workstations.

• 42" flexible hose for deep or recessed fittings
• Built-in LED light to locate fittings in low light
• No-mar foot design protects finished surfaces when resting the tool
• Shoulder strap included for easier portability on site

How long will the battery last and what capacity can I expect?

Equipped with a 20V MAX XR 4.0Ah lithium-ion battery, this kit provides enough runtime to install roughly up to 16 standard grease cartridges per charge, depending on duty cycle and flow setting. The included fast charger gets you back to work quickly, and the battery is compatible with other 20V MAX DEWALT tools.

• Includes 20V MAX XR 4.0Ah battery and fast charger
• Estimated up to 16 cartridges per single charge (actual use varies)
• Variable speed trigger conserves power and improves control
• Battery cross-compatibility with DEWALT 20V MAX lineup

How does the grease gun give me control over flow and maintenance?

Variable speed trigger control allows you to modulate grease output precisely, from gentle priming to full high-flow delivery for rapid filling. Routine care is simplified thanks to the pump filter screen and air-bleeder valve, which reduce downtime for unplanned cleaning or priming after cartridge swaps.

• Variable speed trigger for fine or high-flow applications
• Pump filter screen prevents debris-related clogs
• Air-bleeder valve speeds up priming and eliminates trapped air
• 14 oz capacity supports common cartridges and refill cycles

Who is this for? The DEWALT 20V MAX Cordless Grease Gun (DCGG571M1) is aimed at professional mechanics, fleet and heavy-equipment technicians, agricultural operators, and serious DIYers who need a cordless, high-volume solution for regular lubrication tasks. If you require fast, reliable grease delivery, access to tight fittings, and a battery-powered tool that travels from shop to site, this kit provides a balanced combination of power, runtime and practical features without the constraints of hoses or compressors.
