Does the 2881-20 come with a battery?

No. It is tool-only, so you need a separate M18 battery and charger. Milwaukee recommends High Output XC6.0 packs for the claimed run-time.

Can it use both 4-1/2 in. and 5 in. wheels?

Yes. It accepts both wheel sizes, and the tool-free guard adjusts to match.

How does it compare with a corded grinder?

Milwaukee rates it at 11A corded-equivalent power at 8,500 RPM. In practice it is close for cutting and grinding, but heavy continuous work still favors a corded unit.

Is it worth it over the previous M18 grinder?

The FUEL model adds a brushless motor, more power, and an electronic clutch for kickback protection. If you already own the older grinder and it meets your needs, the upgrade matters most for heavy cutting.

The grinder, a wrench, a flange, and an anti-vibration side handle. No battery, charger, or wheels are included.

Does it have a brake?

No. It has an electronic clutch for kickback protection and overload protection, but no rapid-stop brake.

What reviewers say

Owners and reviewers treat the 2881-20 as one of the strongest cordless grinders on the M18 system, close to corded performance in cutting and grinding. Most criticism centers on the bare-tool packaging and the need for High Output batteries to get the advertised run-time.

What people mention

PowerPraisedOwners say it cuts and grinds like a corded grinder of similar size.
Battery lifeMixedRun-time is strong on High Output XC6.0 packs but shorter on older or smaller M18 batteries.
Kickback safetyPraisedThe electronic clutch is credited with cutting power when a wheel binds.
WeightMixedSome users find it heavy and bulky for overhead or one-handed work.
SwitchMixedThe slide switch with lock-on is liked for long sessions but slower than a paddle for quick cuts.
Accessory changesPraisedTool-free guard and wheel changes are called fast and easy.
