My neighbor gave me this tool, including a storage case a bunch of blades and wheels. I don't know why. I've used it to grind down concrete, cut metal, cut masonry, and remove paint from metal. I like the ability to easily change the handle's position from left to right to the top. I also like that washers are labeled so you know which side faces the tool and which the wheel/blade. I also like the bright yellow color. What I don't like is a there is no ability to lock the switch to on, and b) it's way underpowered. Even slight pressure slows the speed appreciably. I guess it's okay for your average consumer, but it doesn't seem to be professional grade in quality or power.

Good tool and easy to run
I used this to trim 3/4" thick marble and it worked really well. I used this marble for window sills and needed to butt the marble up to the window and around sheetrock so I needed to make some detailed cuts.

I just burned up another brand that was less than two years old. Decided to upgrade to a quality tool. This grinder has so much more cutting power than the old one. I took a chance and replaced a 25 year old Hilti that finally gave up on me. I think that this is going to be a great replacement for the old one.

We manufacture Porcelain signs, but the metal has to be prepped. We have tried various angle grinders and the DeWalt 11 amp 4.5" with the paddle switch out performs all the Metabos and any other grinder out there.

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.
