Overview
The 2984-20 is Milwaukee's 18 volt cordless angle grinder, spinning up to 20,000 RPM with a 671 watt motor. It targets tradespeople who want cutting and grinding power without a cord or a separate compressor.
A 671 watt motor output at 20,000 RPM puts this toward the higher end of cordless angle grinders, closer to what corded grinders deliver, which matters most for cutting metal or grinding welds rather than light deburring. Running on Milwaukee's 18 volt battery platform means it shares batteries with the rest of a Milwaukee cordless lineup, cutting down on the number of chargers a tradesperson needs to carry.

Who it's for
Fits tradespeople already invested in Milwaukee's 18 volt battery platform who need grinding or cutting power on job sites without a power outlet nearby. Less suited to occasional home users who do not already own Milwaukee batteries, since the tool ships bare in this configuration.
Pros and cons
- 671 watt motor output
- 20,000 RPM no-load speed
- Cordless on the Milwaukee 18 volt platform
- Ships as a bare tool, the 20 suffix typically means no battery or charger included
- Runtime depends on battery pack, which is not specified here
Performance notes
Motor output of 671 watts driving a 20,000 RPM no-load speed gives this grinder enough headroom for cutting metal and grinding welds, not just light surface work. Being battery powered removes the cord but ties runtime to whatever battery pack is paired with it, which this listing does not specify.
