Our take on the Milwaukee 2880-20 M18 FUEL 4-1/2" / 5" Cordless Grinder – Paddle Switch, No Lock

The Milwaukee 2880-20 is an 18V cordless angle grinder that Milwaukee claims matches an 11A corded grinder, with a brushless POWERSTATE motor holding 8,500 RPM. It uses a paddle switch with no lock-on, so it stops when you release it, and adds an electronic clutch for kickback protection plus tool-free guard changes. It runs on M18 batteries sold separately; Milwaukee says an XC6.0 HIGH OUTPUT pack gives up to 135 cuts per charge. The best new price was $115.00 at eBay as of November 5, 2026, with 2 stores listing it new.

Questions and answers

Is the Milwaukee 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. For constant all-day grinding, a corded grinder still costs less and never needs charging.
What batteries does it need, and what's in the box?
It takes any M18 pack; Milwaukee cites up to 135 cuts per charge with the XC6.0 HIGH OUTPUT battery. The box has the bare tool only, no battery or charger.
Does it have variable speed?
No. It runs at a single 8,500 RPM, so control comes from technique and wheel choice rather than a speed dial.
Will it take my 4-1/2 and 5 inch wheels?
Yes. It accepts both 4-1/2 in and 5 in accessories with a 5/8 in-11 arbor, and the guard adjusts without tools.
How does it compare to the previous M18 grinder?
The 2880-20 adds a brushless motor, an electronic clutch for kickback and tool-free adjustments over older brushed M18 grinders, with more power and cooler running.
When is it cheapest?
Bare-tool prices move with Milwaukee promotions and holiday sales. The best new price was $115.00 at eBay as of November 5, 2026; kits with batteries cost more.
