The Milwaukee M12 Cordless Grease Gun delivers the highest max operating pressure in its class to help users handle heavy-duty applications and eliminate downtime. The M12 REDLITHIUM battery lets users dispense up to seven grease cartridges per charge, providing up to 25% more pressure and more than 8,000 PSI operating pressure for heavy machinery, cold weather applications and clogged grease fittings. The cordless grease gun has a lightweight, ergonomic handle that offers users greater comfort during prolonged use and an onboard hose storage and shoulder strap for convenience with less mess. Our M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack delivers 25% more power and runs 25% cooler vs our other M12 REDLITHIUM CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM XC battery in a lighter and more compact package. The 12-volt battery pack delivers fade-free power and runs substantially cooler through demanding applications, allowing you to push your cordless power tools throughout a wide range of applications. Its compact, lightweight design allows you to work in tight workspaces and reduces fatigue. In addition, the M12 REDLITHIUM HIGH OUTPUT CP2.5 is built with a resistant housing, providing increased protection against exposure to common oils, greases, and solvents found in automotive and manufacturing environments.
