Is the 2880-20 worth it over a corded grinder?

If you already own M18 batteries, yes: it cuts and grinds close to an 11A corded unit without a cord. If you work mostly at a bench with power nearby, a corded grinder costs less and never needs charging.

Does the 2880-20 come with batteries?

The 2880-20 is the bare tool and ships without batteries or a charger. The 2880-22 kit includes 6.0 Ah batteries and a charger.

How long does it run on a battery?

Expect short runtime under continuous heavy grinding on a compact pack. A 6.0 Ah or larger High Output battery gives the most usable run time; keep spares charged for long jobs.

What wheels does it take?

It uses 5-inch wheels with a 5/8"-11 arbor, the standard size for most cutting and grinding discs. Check the wheel's RPM rating is at least 8,500.

Is it too heavy for one-handed use?

It is heavier than a corded 5-inch grinder, more so with a large battery. Most users treat it as a two-handed tool for cutting and heavy grinding.

When is the best time to buy it?

Milwaukee tools see the deepest discounts around major holiday sales and during kit promotions. Buying the bare tool is cheapest if you already have M18 batteries.

Our take on the Milwaukee M18 FUEL Grinder Paddle Switch 2880-20

The Milwaukee 2880-20 is an 18V cordless 5-inch angle grinder in the M18 FUEL line, built around a brushless motor that Milwaukee rates at corded-equivalent 11A power and 8,500 RPM. It uses a paddle switch with a no-lock design, so it stops when you release the paddle, and it runs on the M18 battery platform. The 2880-22 kit bundles 6.0 Ah batteries. It is one of the strongest cordless grinders you can buy, and it costs accordingly.
