Overview
The Milwaukee 2686-20 is a cordless angle grinder built for the M18 18 volt battery platform, spinning up to 11000 RPM. The 20 suffix in the model number is Milwaukee's standard way of marking a bare tool sold without battery or charger.
The listing does not break out disc diameter or motor type, so buyers should confirm the exact wheel size this model accepts before ordering discs or accessories. An 11000 RPM no load speed is in line with compact angle grinders in Milwaukee's cordless lineup.
- 18V M18 battery powered
- 11000 RPM no load speed
- Bare tool, no battery included
- Milwaukee cordless platform
Who it's for
Tradespeople already invested in Milwaukee's M18 battery system who want a cordless grinder for cutting, grinding, or sanding tasks. Less useful for buyers with no existing M18 batteries.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs on the M18 battery platform
- 11000 RPM matches standard grinding discs
- Cordless for job site flexibility
- Sold as bare tool, no battery or charger included
- Disc size and motor type not specified in listing
- No reviews yet to confirm run time
Performance notes
At 11000 RPM the motor spins fast enough for standard cutting and grinding discs, and battery power removes the cord from the equation on a job site. Since it ships as a bare tool, run time depends entirely on whichever M18 battery the buyer already owns.
