Milwaukee 18V Grease Gun, High-Pressure Cordless Lubrication up to 10,000 PSI

The Milwaukee M18GG-0 is a cordless grease gun designed for high-pressure lubrication tasks. It can dispense grease with up to 10,000 PSI, making it suitable for demanding industrial and automotive applications. Being a bare tool, it requires your own M18 battery and charger.

Key specs include: 18V M18 platform compatibility, maximum output pressure up to 10,000 PSI, bare tool (battery and charger not included), and a construction designed for heavy-duty use in industrial and automotive contexts.

Yes. Since it's a bare tool, you’ll use your own Milwaukee M18 battery and charger to power it. This lets you integrate it into your current M18 system.

Typical setup involves attaching a compatible M18 battery, connecting the grease hose and coupler, loading grease (cartridge or bulk), priming the gun as needed, and using the trigger to dispense grease. After use, relieve pressure and disconnect the battery if you’re storing the tool.

It excels at heavy-duty lubrication tasks such as automotive chassis and drivetrain points, industrial machinery, and other equipment that require high-pressure grease delivery to hard-to-reach points.

Consider a longer or flexible grease hose, replacement nozzles or couplers, extra grease cartridges, a battery and charger if needed, and compatible extension tools to reach tight spots.

If you’re weighing options on Fepy, you can compare this bare-tool Milwaukee option to similar models such as the Milwaukee M18GG-1 (battery-included variant) and other brands like DEWALT 20V MAX grease guns to see differences in battery setup, price, and included accessories.

Wear eye protection and gloves, ensure all connections (hose, coupler) are secure, operate within the rated 10,000 PSI, use the correct grease type for your application, and disconnect power when not in use or when performing maintenance.

After use, clean the exterior and fittings, inspect hoses and couplers for wear, ensure the nozzle is clear, store in a dry location, and follow the manual’s guidance on lubrication and part replacement to extend tool life.

If you already own compatible M18 batteries and chargers, a bare-tool option can be more cost-effective and lets you leverage your existing M18 system while delivering high-pressure performance when you need it.

Use the correct grease type, load the cartridge or bulk grease as per the manual, prime the gun to remove air pockets, and then operate at the appropriate pressure. Always follow the on-tool guidance and safety precautions when refilling.
