Ran through rock quarry plant and still works
by Bryce Seats (5 out of 5 stars)

@dewalttough are tried and proven to be the best in my toolbox. I will never buy anything else. This grinder has since February of this year already had a hard life. Then last Friday it got ran through my entire rock quarry plant. Which consisted of getting hit with rock and submersed under water and pushed out by a large auger and found in a rock pile before it was shipped out to be used in concrete. Let it sit for a few days and it still works. And that's the battery that was on it when it happened. All still work. Impressive. The trigger is a little sticky for turning it on but still works. Thanks @dewalttough for making a great product. #dewaltgrinder #dewaltbrushless #dewalt20v #toughtools #plantmechanic

The Boss!!

DEWALT DCG413B 20V Angle grinder

I have several angle grinders, all electric. Hesitated to purchase a battery powered but my other DeWalt tools do so well and the reviews were so good I thought I would go for it.

GLAD I DID! This angle grinder is the boss. No more do I need to find an extension cord to grind, cut off or sand some simple project!

It's so easy to operate and has all the power I need for 70% of my projects.

Six Minute Runtime on a 4A Pack
by Me (4 out of 5 stars)

I used this with an arbortech turboplane to grind down a 16-18" diameter maple stump ~2-3 inches so it sits below ground. According to the tool box, the tool uses up 800W (their website says 850W) so the DEWALT 4A battery should last around six minutes, plus or minus a minute or so. This is almost exactly what I got out of those batteries. The higher capacity batteries ran a bit longer but not much more. The batteries get quite hot right after use and the charger will go into thermal delay to protect the packs.

For a battery operated tool, it had plenty of power comparable to a corded model. I like the two safety features, the anti-kickback and the brakes but I wish they kick in faster instead of taking 1.5 seconds to full stop.

Every Contractor Needs this Tool
by Rollogic (5 out of 5 stars)

While buying other DeWalt power tools I didn't think to get this one. Then when it came time to cut some cement backerboard I forgot I needed this. It has been great for doing just that. It has also been excellent for cutting metal and masonry. It is easy to switch out the blades. There is a brake to hold it in place to switch out from a metal, diamond, or masonry wheel. The guard is an easy spring loaded adjustment too. High RPMs to cut anything and I have not experienced any bogging down while cutting. Very powerful. My favorite part - no cord! The battery in the picture was bought separately, but I use the 6.0AH to keep up with the demand of this beast.

Overall a much needed tool in your arsenal. I recommend and would buy it again.

Overheats batteries and drains the big ones in minutes!
by norty661 (1 out of 5 stars)

This grinder will either overheat or drain one of the big batteries in just a few minutes which completely negates it being cordless. I use my Harbor Freight grinder more than I use this piece of junk. Same exact story with the Dewalt cordless hammer drill.

Very nice

An incredible angle grinder and it's cordless! Very pleased with this grinder. I upgraded to a 6.0 battery and it will grind for a good while before needing to be recharged. More power than I imagined and much more quiet than other corded angle grinders. It's worth every penny.

Perfect! Make sure you have some 5AH batteries.
by Nick James (5 out of 5 stars)

This angle grinder made a great addition to my 20v tools from DeWalt. There isn't much to put in this review that is different from what you can find on YouTube etc...

One this I will say is that the 2AH batteries will give you low run times. While using this with the 2AH battery and a cutoff disk, the grinder would continually stop from binding on the aluminum sheetmetal I was cutting (almost like a lack of power). The 2AH batteries (I tried 2 different ones which both had a full charge) had the same issue. When I switched to the 5AH battery, the tool had much more power and had zero issues. I guess this is a drawback with the battery powered grinders... Not really a big deal for me because the advantage of using a cordless angle grinder has a ton of advantages which heavily outweighs the small issue with the 2AH battery.

This tool is a must have. Also grab a 5AH battery or higher.

It's a great little grinder
by Layton (5 out of 5 stars)

Coming from using a corded Ryobi angle grinder, I was looking for something a little more portable. It's a great little grinder. I keep flap disc on this and a cut off wheel on the corded grinder. I highly recommend this combination. I prefer the trigger of the corded to the paddle switch and safety of the dewalt. I'd recommend 5ah batteries as well. The guards click adjustment works very well.

Great grinder
by Bruce (5 out of 5 stars)

Because I have a Dewalt 20 volt weed trimmer that is sorely lacking in power, I was hesitant to buy this grinder. Turns out I needn't have worried. I'm currently using it to trim some slate slabs which are up to 2" thick and it works quite well. Good battery life (5 Ahr batteries) and lots of power. I also tried it on some 3/16" steel and it worked fine.
