The Milwaukee M18 FUEL 2880-20 wins because it closes the old gap between cordless convenience and corded power while adding safety features no plug-in grinder can match. ToolShedTested ranked it the best overall cordless grinder at 4.8 out of 5, measuring 80 to 95 percent of corded cutting power in real work. FindingDulcinea placed the same M18 FUEL platform in its premium tier at 4.8 out of 5.
The safety story is what seals it. The RAPIDSTOP electric brake halts the wheel in under two seconds, and an electronic clutch cuts power the instant the disc binds. ToolShedTested called that AUTOSTOP-style kickback control a genuine upgrade you cannot get on corded models. For a tool that spins an abrasive wheel inches from your hands, that matters more than a few extra amps.
It is also the lightest grinder in this group at 3.1 pounds bare, so it stays controllable through long jobs and overhead cuts. If you already own M18 batteries, it is an easy call. Even if you do not, the mobility and braking justify buying into the platform for most serious buyers.
What It Won't Do
It ships as a bare tool, so first-time M18 buyers pay extra for a battery and charger before they can run it. FindingDulcinea flagged that up-front cost as the main reason a corded grinder can still make more sense for a fixed-bench user.
The DeWalt DWE402 is the value pick because three independent test teams keep landing on it, and it delivers the most cutting power per dollar in the group. FindingDulcinea named it Best Corded Power at 4.8 out of 5, Benchmark Abrasives called it the Best All-Around choice, and Bob Vila tagged it the heavy-duty pick.
Its 11-amp motor is the highest corded amperage here and spins to 11,000 RPM, so it bites into steel without bogging down. Bob Vila also singled out the dust-ejection system that keeps grit out of the motor, which is a big reason this tool lasts at a price around eighty dollars.
You give up a brake and you carry a heavier 6.2-pound body, but for shop and bench work where an outlet is always close, the DWE402 buys more raw grinding for less money than anything else we looked at.
What It Won't Do
The DWE402 has no electric or kickback brake, so the wheel coasts for several seconds after you release the paddle. At 6.2 pounds it is also the heaviest tool here, which you feel during overhead work.
