The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The Milwaukee 2880-20-NBX runs on the M18 platform at 18V, spinning its wheel at 8500 RPM for general-purpose grinding, tile cutting, and surface prep. The tool-only pricing at $166.25 targets existing Milwaukee users who can drop in a battery they already own.
At 5.27 pounds, it sits in the standard weight range for a cordless grinder of this class. The 4.7-star rating from 251 owners points to consistent satisfaction with build quality and day-to-day performance, though the 50 units bought last month indicate it is a more selective choice than a volume seller.
This is a bare-tool listing, so factor battery and charger cost into the total if you are new to the M18 system. Buyers coming from a corded setup should compare the RPM and runtime trade-offs carefully before committing.

Performance notes
The 2880-20-NBX draws 18V from the M18 platform and spins at 8500 RPM. The 5.27-pound body is typical for an 18V cordless grinder. Performance scales with the M18 battery capacity chosen, with higher-Ah packs extending runtime on heavy material removal tasks.
What buyers say
Owners consistently highlight the fit with the existing M18 battery lineup as the main draw. Some buyers note the RPM feels adequate for light to moderate grinding but comment that heavy stock removal works better with a corded tool. Build quality and the Milwaukee brand reputation are frequently cited positives.
