Dewalt DCGG571B Cordless 20V MAX Grease Gun – Tool Only

The Dewalt DCGG571B 20V MAX* Grease Gun is built for high-demand lubrication tasks where uptime and reliability matter. Delivering up to 10,000 PSI, this cordless grease gun powers through clogged fittings with ease, while the high-volume pump moves up to 5.0 oz. per minute, making it an ideal choice for machinery maintenance, heavy equipment servicing, and automotive applications. The 42″ flexible hose provides extended reach for those hard-to-access grease points, and the variable speed trigger allows for precise flow control during detailed work.

Designed for field service mechanics, maintenance crews, and operators working in remote or industrial environments, the DCGG571B combines portability with power. The built-in LED light helps locate grease fittings in low-light areas like engine bays or undercarriages, while the integrated pump filter screen protects the system from debris and contaminants. A no-mar foot design allows the tool to rest safely on flat surfaces, and the air-bleeder valve assists with priming after cartridge changes—keeping productivity up and downtime to a minimum.

Note: Battery and charger are sold separately.
