Performance notes
The 2888-20 delivers 8500 RPM from its 18V lithium-ion motor rated at 198 watts. The 5.4-pound body distributes weight in a manageable way for most grip styles. Performance scales with the battery capacity used, and heavier removal tasks will draw more current from the pack.
What buyers say
The 500 monthly purchases and 4.8-star score reflect genuine owner satisfaction. Buyers frequently note the tool's dependability on the M18 platform and its build quality. Where negative feedback appears, it tends to focus on runtime limitations under sustained load rather than the grinder's core mechanics.
