What reviewers say

Sourced tester consensus for each — the "what people who used it think" layer, not just specs.

Milwaukee M18 FUEL 2880-20 4-1/2 in./5 in. Grinder Paddle Switch No-Lock (Tool Only)

Only one whitelisted tester, Pro Tool Reviews, covers the exact 2880-20, and only inside a Milwaukee lineup comparison rather than a standalone bench test. Editors endorse its runtime and safer paddle-switch design, but every performance figure (135 rebar cuts, 11A, 8,500 RPM, $199) is Milwaukee's own claim, not independently measured. (1 sourced review.)

Praised: Paddle switch gives a safer setup for shorter grinding and cutting bursts; Editors endorse the runtime (Milwaukee-claimed 135 cuts in 1/2-inch rebar per XC6.0 battery).

Flagged: Coverage is a lineup buying-guide, not a standalone bench test, so there is no independently measured performance for this exact model.
