Does it come with a battery?

No. It is tool only, so you need a DEWALT 20V MAX battery and charger, sold separately.

What is the maximum pressure?

Up to 10,000 PSI, enough to push through clogged fittings and stiff grease.

How fast does it pump grease?

Up to 9 oz per minute in high-flow mode, with a slower speed for more control.

What grease cartridge does it take?

It uses standard grease gun cartridges and can also be bulk-filled; the 47-inch hose fits most fittings.

Is it worth it over a manual grease gun?

For frequent lubrication on equipment, the cordless power and pressure save time and hand effort; for occasional use a manual gun is simpler.

Does it work with all DEWALT 20V MAX batteries?

Yes, it is compatible with the DEWALT 20V MAX battery platform.

Our take on the DEWALT 20V MAX Cordless 2-Speed Grease Gun – Tool Only (DCGG581B)

The DEWALT DCGG581B is a bare-tool cordless grease gun running on the 20V MAX battery platform. It pushes up to 10,000 PSI to clear clogged fittings and offers two speeds plus a variable-speed trigger, with high-flow output up to 9 oz per minute. A 47-inch flexible hose and an LED light help in tight, dark spots. It suits mechanics and equipment owners already on the 20V MAX line; rivals like Milwaukee's M12 and M18 grease guns are more compact but use a different battery system.
