DEWALTAngle Grinder, 7-Inch, 13-Amp, 8,000 RPM, With Dust Ejection System, Corded (DW840)

Like always Dewalt tools has very high quality and high performance, I’m very happy with this product!

It's got enough weight that you don't have to lean into it while pulling back through flagstone and harder sandstones. The 7-in blade capacity gets through over 2 inch thick material. I would keep two of these on the job in case the switch and brushes got too much stone dust in it to work reliably. Not too much trouble to clean it out. With two guys cutting on the job I got this one to have a third so that we have a backup handy but I don't feel the need to have two backups.Good power and long handle make for a useful machine. This is no lightweight,agile little 4.5" machine. I've used the heck out of this and don't feel a need for expensive brands like Metabo.

Handled my job well. Basement floor with lots of cracks and unlevel concrete used with a diamond grinder wheel

I am going to say that I was amazed and more than pleased by the customer service associated with this purchase. The grinder is a good tool, but the particular one I received had (I think) a defective bearing or shaft in that at the second use it began to vibrate and progressively got worse. I could wiggle the shaft and the abrasive disc was wearing unevenly. This was at about 45 days of purchase. I tracked the warranty information and the best Dewalt would do is have me ship it to them at my expense. They would repair it and ship it back to me at my expense. the process was estimated to take 10-14 days and I would have a repaired item. I called Amazon got through with about a 45 second wait, pointed out the 90 day money back guarantee and asked to return the grinder for credit. The rep asked if what I really wanted was an exchange, which was exactly what I wanted. She gave me an overnight UPS return sticker and I sent it off in the morning. By the next afternoon, I had a brand new grinder which works perfectly. I might add that I live on a country road far from any airport. I even got the $20 off promotion I had had on the original purchase. This was fabulous. This was really above and beyond. I honestly don't know how they do it.

This unit is incredibly powerful but very controllable. I used it with a concrete grinder to remove the remnants of Thinset mortar. Using a shroud and vacuum attachment allowed me to remove the mortar and smooth the concrete with minimal dust.~JSmith
