Milwaukee 2880-20 M18 Fuel Brushless Lithium-Ion 4-1/2 in. / 5 in. Cordless

The Milwaukee 2880-20 M18 Fuel 4-1/2-inch to 5-inch cordless grinder provides a portable solution for metalworking and surface prep. It runs on the M18 battery system, giving users who already own Milwaukee tools a straightforward way to cut and grind without dealing with power cords.

Safety and tool longevity are central to the design. An electronic clutch engages to protect against sudden kickback during binding, while built-in overload protection helps prevent motor damage during heavy use. For user comfort, the included side handle features anti-vibration technology to reduce fatigue during extended grinding sessions.

For accessory setup, the tool utilizes a standard 5/8-inch-11 spindle, allowing quick compatibility with common grinding wheels and discs. Keep in mind that this listing is for the bare tool only, meaning you must supply your own M18 batteries, charger, and abrasive accessories.

Verdict: The Milwaukee 2880-20 is an excellent choice for anyone already invested in the M18 battery lineup who needs a reliable, feature-packed cordless grinder for standard 4-1/2-inch and 5-inch applications.

• Already own Milwaukee M18 batteries and chargers.
• Need a cordless grinder with built-in kickback protection.
• Want an anti-vibration side handle for comfortable operation.
