Power packed with long life
I bought this polisher mainly to polish my boat without dragging cords everywhere around the water. I can definitely say I am NOT disappointed. Plenty of power with long battery life.

I loved this tool!
I purchased Milwaukees cordless 7" polisher to buff a car that we had painted at the shop. Its great not having a cord hanging around your neck all day. The other 3 employees all thought it was the best thing since sliced bread. One of the best tool purchases

I used it with the 3m 3 step polishing system worked great .kept the speed low 1500 to 1800 rpm . Mid capacity or higher battery is probably best i used one of the lower ones and it runs outa juice a little soon. Not heavy ,balanced ,no cord ,very satisfied!

Corded power, without the tangle and mess
Great Rotary polisher, wish it was dual action but as an experienced paint corrector I have no problem getting excellent results. Love th cordless factor. Would be nice if Milwaukee had a wider range of pads, but other vendors supply what I need. Don't hesitate to buys this polisher. Make sure you have a t least two 5.0 batteries if your doing heavy corrections and polishing jobs.

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.
