Best grinders on the market for design, build, quality and cost. Love Dewalt!!
Doesn't get better than Dewalt. Dewalt always tops my list of well designed, well built equipment that's affordable for the DIYer as well as the professional. Balanced perfectly in my hand, which tends to be on the smaller side. Because the size and weight are so well thought out, the added layer of safety is a given. I've wanted a grinder for a while, so when I needed to strip down the rv gate, this was a no brainer. I had initially started stripping it down by hand, but gave up after a couple of hours. I finished stripping the whole gate in a day once it was delivered. Have the right tool makes a difference. Having the best tool is just smart! I'm sure I will be using it for many more projects because the additional wheels you can change out makes this especially versatile.

Great tool. Love it. The guard is easy to adjust for convenience
Huge upgrade from my hobo freight corded one that is 20 years old. It has plenty of power and the battery lasts longer than I expected.

If you need to cut or grind anything, get this!
This is a great tool! I wish I had bought one years ago. It is easy to use and will tackle anything.

DeWalt quality
It’s DeWalt, obviously built to last, lightweight, easy to operate and battery powered use anywhere you need.

Great Dewalt Tool
One of my most used Dewalt tools. I bought it for cutting bricks for a new patio but it has so many more uses. The arbor/nut with include allen wrench makes it easy to change out cutting wheels. Doesn't seem to use battery power excessively either.

Worked with my 20V DeWalt batteries and was reasonably inexpensive
If you need an inexpensive legitimate DeWalt angle grinder this one does the job. I’m invested in the DeWalt 20V platform and needed an angle grinder for a specific job at the house. This was within my price range and did the job demo’ing some stuff around the house.

Great tool with no cord!
I've used corded angle grinders for many years and I never expected a cordless angle grinder to be worthwhile. I was pleasantly surprised that this angle grinder works amazingly well. With steady use, the battery will discharge after several minutes, so it's helpful to have a second battery on standby. However, for most standard applications it's worth not dealing with a cord getting in the way. This has plenty of power to work as expected.

Apesar da ferramenta ser profissional não recomendo para uma serralheria. Pois consome muito bateria. Mas para quem usa para soldar um pouco daqui a pouco usa pra cortar um cano ou sabe se lá oq. É muito versátil a potência e excelente e a praticidade de não ter bateria e ótima. Mas é necessária bastante bateria no mínimo 2 de 4ah e para uso constante não dá tempo de carregar uma enquanto usa a outra. Acredito que em uso sem desligar dure uns 20, 25 min.

Excellente meuleuse Dewalt, très bien balancée et surprenamment légère pour la puissance qu’elle offre. Le frein de sécurité (kickback brake) fonctionne parfaitement et ajoute une belle tranquillité d’esprit. J’aime beaucoup la gâchette à deux étapes, ça évite les départs accidentels. Une vraie bête pour le métal, le bois ou même la pierre !

Muy buen producto, funciona bien y es original. Solo considerar usar baterías de 5ah ya que las de 2 se acaban muy rápido
