Milwaukee 2446-20 M12 12V Cordless Grease Gun (Tool Only)

Power and precision on demand

Meet the Milwaukee M12 2446-20 cordless grease gun, a tool-only solution designed for dense lubrication tasks on the job site. With a compact profile and the proven M12 platform, this gun aims to reduce fatigue while delivering steady, controlled grease flow. Its lightweight build and thoughtful ergonomics make long sessions feel more manageable without sacrificing performance.

High-pressure performance you can rely on

When you need high pressure, the 2446-20 is built to deliver. It can generate over 8,000 PSI for heavy-duty applications, helping you break through stubborn fittings and speed up routine maintenance. Paired with a run-time profile that dispenses up to seven grease cartridges per charge, you can work longer between charges in the field. Compare it with typical cordless grease guns, and you may experience up to 25% more pressure and run-time for demanding tasks.

Lightweight, balanced design

The tool feels nimble in balance and handling, measuring about 14 inches in length and weighing roughly 7.2 pounds. This thoughtful proportion aims to reduce fatigue during extended use, making it easier to maneuver around fittings and joints without sacrificing control.
