Details
The Milwaukee 2780-21 M18 FUEL 4-1/2 in - 5 in. Grinder with No-Lock Paddle Switch is the industry's first cordless grinder with the power to tackle heavy-duty grinding applications. This brushless grinder delivers 8500 RPM to tackle fade-free grinding, surface prep and cut-off jobs. A slim ergonomic handle and large paddle switch ensure comfort with or without gloves, and the shock absorbing handle reduces vibration. The no-lock switch is fully OSHA compliant and ensures a dropped grinder won't continue spinning. A tool-free guard helps users make quick adjustments while the 5/8 in. - 11 arbor accepts common cut-off wheels, grinding discs and wire cups. Legendary Milwaukee durability is found throughout, as this grinder uses many of the same components found in our durable corded units.

Powerhouse
I bought this because we are building a house and don't have power yet. I needed something to cut 1/2" rebar and didn't feel like shelling out the bucks for a generator just yet and needed something to replace my cheap electric angle grinder.
The weight balance feels good. I really like the quick adjustment for the guard. This thing cuts through 1/2" rebar so quick I was surprised. Another feature I like is that when you release the paddle handle the blade stops immediately. Really a nice feature.
Very happy with this purchase. Milwaukee tools are worth the premium over the stuff you find at the discount big box store.

Great Product
Batteries last a long time. It's great to not have to worry with cord or power source. Power is amazing for a rechargeable battery

Sleek and well balanced
The cordless grinder will make all my future grinding and cutting jobs a breeze.My old grinder had an appetite for the cord and liked to get me all tangled up.
I will now be able to concentrate on the task at hand. And this cordless grinder will be an extension of my hand.

Interested in knowing the arbor size (for specifying cut-off wheels). I believe my current is 7/8".
I assume that this tool uses thin cutoff in addition to other thicker wheels for steel and concrete?
