The Dewalt DCGG571N Grease Gun allows you to perform daily maintenance grease applications in up to half the time of a manual grease gun. It features a powerful motor that delivers 10,000 max psi to power through clogged grease fittings. The high-volume pump pushes up to 5.0 oz/min for high-flow applications. Get up to 16 cartridges per charge with a single battery (4.0 Ah). The variable speed trigger offers precise control of the grease flow, and the 42" extra-long hose is designed for hard-to-reach fittings. An LED light helps to illuminate fittings that are difficult to locate, and an included shoulder strap provides convenience for carrying the unit during applications that require climbing or maneuvering around a worksite. The built-in bleeder valve allows the user to bleed excess air that can often become trapped in pump valves, affecting the pressure and speed of application. The innovative pump filter screen on the unit helps to keep dirt from passing through the pump mechanism. The integrated no-mar foot design allows operators to rest the tool on flat surfaces. This is a Bare Tool - No Battery or Charger Supplied.
