Equal to Milwaukee's reputation
Plan on spending many hours on scaffolding working on old brick. Look forward to hours of no power cords needed with a Milwaukee 18 volt right angle grinder.

I love the convenience of this tool, much more safe than tugging a cord around behind you. The only issue that I have with it is that it goes through batteries very quickly.

Corded power untethered
Feels, handles and runs like a no compromises tool. Doesn't seem to give up any performance to a corded tool. I don't use a grinder a lot but when needed it usually is in situations where ragging a cord is a nuisance. This does it for me. Good ergonomics. I haven't run jobs that allow me to comment on battery life but I always have a 2nd battery available anyway. Yes it;'s fairly loud but it's a grinder.

Milwaukee power
The fuel grinder is awesome for power and reliability... My only complaint would be the safety switch is difficult with gloves. I should have maybe bought the slide switch but I am more that happy with it

Cut the cord
Works just the same as my corded grinders. Cuts and shapes with at least the same power. Was especially useful grinding out mortar on a chimney. Decent run time with the 4amp battery

Milwaukee batt tools the way to go
Battery tools are great for those hard to get to places with no electricity. I still use my hard wired tools for shop work. I have used many other brands at work. I prefer Milwaukee.

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.
