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.

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?

BEST ANSWER: the arbor size on this unit is 5/8-11.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
