Overview
The Milwaukee 2886-20 is an 18 volt battery powered grinder spinning at 8500 RPM, weighing 19.19 ounces as listed. It holds a 4.8 star average across 330 ratings, with 200 units bought in the past month.
The model number and bare weight under 20 ounces point to a bare tool from Milwaukee's M18 cordless line, sold without the battery and charger that power it, which is common for buyers already invested in that platform. Milwaukee is a well regarded name in cordless power tools, and the 8500 RPM speed is in line with an angle grinder built for cutting and grinding metal.

Who it's for
Fits someone already on Milwaukee's 18 volt M18 battery platform who needs a grinder body to add to it, since the model number and light bare weight suggest the battery is sold separately. Not the right pick for someone wanting an all in one kit with battery and charger included, unless the full listing confirms that.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4.8 star rating, the strongest in this batch
- 8500 RPM suited to metal cutting and grinding
- Light bare tool weight for extended handheld use
- Weight suggests battery sold separately, adding to total cost
- No blade or disc size specified
Performance notes
At 8500 RPM on an 18 volt system, this grinder is geared for cutting and grinding tasks typical of angle grinders in this class. The 19.19 ounce weight lines up with a bare tool rather than a kit, which keeps it light in hand but means the battery is likely a separate purchase.
