Overview
Milwaukee's 2880-20-NBX is a battery powered grinder running on 18 volts at up to 8500 RPM, weighing 5.27 pounds.
The NBX suffix on Milwaukee tool numbers typically marks a bare tool sold without battery or charger, so budget for those separately if you do not already own Milwaukee's 18 volt system. At 5.27 pounds it sits on the heavier side for a cordless grinder, which trades some one handed maneuverability for the torque needed on tougher cutting and grinding jobs.
- 18 volt battery power
- 8500 RPM top speed
- 5.27 pound weight
Who it's for
Tradespeople already invested in Milwaukee's 18 volt battery platform who want a cordless grinder for metal cutting, grinding or surface prep. Less suited to first time buyers without existing batteries, since this appears to be a bare tool.
Pros and cons
- Cordless freedom on Milwaukee's 18 volt platform
- 8500 RPM for cutting and grinding work
- 5.27 pounds is heavier than some cordless grinders
- Likely a bare tool, no battery included
Performance notes
8500 RPM at the disc drives cutting and grinding speed, while the 18 volt battery platform trades the cord for run time limited by battery charge. At 5.27 pounds, expect more arm fatigue on overhead or extended work than with Milwaukee's lighter corded options.
