I received this grinder as a gift about 6 months ago. I am a welder and complain often about my corded grinder(which is a beast) because I have leads, ground cables, and other trip hazards around so the last thing I want is another cord to trip on.
I specialize in stairs and railings which, as you can imagine need to be clean as clean can be prior to paint or powder. I run, on average, 4-8 4 AH packs through this little guy 5-6 days a week so I believe at this point, I'm a qualified opinion.
Weight and Balance:
Light weight. I actually think it's almost a little too light. I run the 4 AH packs partly for runtime, but also for heft. I like the balance better with the bigger pack. It's by no means bad with the smaller packs but my personal taste is to run the 4's.
Durability:
This thing is beaten daily and still runs like new. No head noises, no loss of power. I have had 0 issues with the switch. Through steel, aluminum, and stainless it just grinds away.
There is visible wear on the rubber coating(meaning it's now smooth) which is to be expected with the level of use. It's been dropped, had things dropped on it, and even took a bath in Monster one day and it just keeps on ticking.
Battery life: I use everything from cuttoff wheels to flapdiscs, hard discs to sanding pads. Sanding pads by far have the greatest battery life. Cuttof wheels last forever if you're cutting light gauge, but it eats them cutting thick stuff. I break out the corded if cutting 1/4 or thicker. Flapdiscs are in the middle of the road and hard discs aren't bad as long as you don't lay on it. If you push the heck out of it, it's not too great.
Brake:
This is great. I save my pads, and my table because I'm not constantly stopping the head on the table. It also doesn't kick much at all when the tool catches.
Guard:
It's a guard. I'm sure it works however I can't speak on that. It's easy to take off(*DISCLAIMER: I recommend always using a guard when possible.) For my purposes a guard on any grinder is in my way. Mine is still shiny, unlike the rest of the grinder.
Summary:
All in all a great grinder and a good purchase. My title says I will buy again because I will eventually wear it out. Judging by how it has performed, I'm guessing that won't be for a long time unless I drop something big on it. Good job Dewalt. Solid tool as always.

I needed to drill holes to run wiring in my new addition. As a petite female, I was looking for an alternative to the cordless Dewalt drill that my husband uses which basically takes a lot of strength to drill the holes and not have the drill ripped out of your hand. All of our cordless tools are Dewalt, so I obviously looked to Dewalt for a solution. This tool is awesome. First, though it is heavy, it is ergonomically designed so the weight is evenly distributed. Second, it is easy to hold and to drill the holes, even in tight spaces. One thing which is an added bonus - the flexvolt batteries. I probably would never have bought the batteries but now that we own them, we can't live without them. They last forever in the smaller drills and cordless tools and provide enough power to easily drill through three two by fours! I drilled the electrical holes in my new addition which included a bedroom, new bathroom, dining room and laundry room on one battery. Awesome tool - highly recommended.

Love the soft start and stop
[This review was collected as part of a promotion.] This is my second 20V Max grinder. I own the DCG412B as well. This one is longer, but I find that it is at last easier to hold, and better balanced. My favorite part is that it has a "soft" brake when you let off the paddle. It spins the wheel down gently, yet quite quickly. The gearing that provides the angle transmission seem to mesh better than the gears in my other tool. This one is smoother and quieter.
Clearly this one has more power and spins faster as well. I haven't burned through a whole battery in one go yet, so I can't comment on runtime just yet, but it obviously isn't worse than my other tool. And of course I expect it to be better because, XR.

Perfect balance
[This review was collected as part of a promotion.] I have been using most of times this grinder during my daily works as welder, I love the way it feel firm and powerful, combined with lightness and handiness.
Also been using different grinder brands but none of them gave me the same feeling on terms of performances.

DeWalt Quality
[This review was collected as part of a promotion.] I’m a big fan of the 20v DeWalt tools. I needed a portable grinder for miscellaneous work around the house. I bought this and have not been disappointed.
It is durable and well built. I’ve used this for everything from cutting tile to stripping paint with a wire wheel. It’s certainly up to the task.

Overall I like the grinder. I have used it to cut a few carriage bolts and two pieces of 3/4" mild steel rod. Good power, paddle safety switch is not too annoying. Misses are, hex wench for the collet not included, no onboard storage for said wrench.
