Pros & cons
Milwaukee M18 Fuel 2880 Angle Grinder
- ✓Genuinely replaces an 11A corded grinder for cutting and light fab work — the cordless-parity claim holds in owner use.
- ✓The Rapid Stop brake halts the wheel in seconds, and crews cite it as the reason safety managers approve this model.
- ✓Paddle switch with no lock-on satisfies jobsite safety rules that ban lock-on grinders.
- ✓Tool-free guard adjustment actually stays put under vibration, unlike many rivals' detent guards.
- ✓Shares batteries with the rest of M18, and it pulls hard on High Output packs without tripping protection.
- ✓Overload protection prevents the burned-out-armature death that kills corded grinders in heavy use.
- ✗It devours batteries — sustained grinding drains a 6.0Ah High Output pack fast enough that corded still wins for bench work.
- ✗Street price around $199 bare is a big step over corded grinders of equal power.
- ✗No variable speed on this model; you need the 2888 for RPM control on polishing work.
- ✗Heavier than corded equivalents once a big battery is fitted, which fatigues overhead cutting.
- ✗The paddle takes acclimation if you're coming from a slide-switch grinder — some owners find long sessions hand-cramping.
- ✗Wheel-change wrench storage is nonexistent; owners improvise.
DeWalt DCG415 Angle Grinder
- ✓Class-leading 9,000 RPM and 1,350W output with a big battery — Pro Tool Reviews measured it at the top of the 20V class.
- ✓The Kickback Brake genuinely fires on wheel pinches; owners describe it saving wrists on rebar cuts.
- ✓Power Detect scales output up with 8Ah+ packs, so the tool grows with your battery investment.
- ✓At under 4 lbs bare it is light for the power class, helping overhead and fatigue-prone work.
- ✓E-Clutch stops the driveline on bind-ups instead of spinning the tool around the wheel.
- ✓One-touch guard rotates without tools and locks positively.
- ✗Headline power requires an 8Ah or larger battery — on compact packs it is a mid-pack grinder.
- ✗Runtime under sustained load is the class complaint: grinding is where cordless still taxes batteries hardest.
- ✗The brake's abrupt stop takes getting used to and can jerk cut-off wheels if you feather the paddle.
- ✗Kit pricing with the big battery pushes $279+, eroding the value story.
- ✗DeWalt's 3-year warranty trails Milwaukee's 5-year coverage on the competing 2880.
- ✗No variable speed for surface-prep and polishing tasks.
