DeWalt DCG413B 4-1/2" 20V MAX* Brushless Cut Off Grinder w E-Brake (BARE)

I bought this a couple weeks ago to replace my corded grinder that I lost when my shop burned down I had mix of power tool brands before mostly dewalt but had other brands I can tell you I will only be replacing with dewalt I had the old 18v system and they were amazing then I had just started replacing with the 20v system when my shop burned down I will only buy the 20v system they are unstoppable.

I got it to dig myself out of a nasty access hole where I couldn't get mains power - hanging 30 feet down, and off the facade of a building, removing some very shaky old metal work. Now I don't think more than a couple of days have passed before I've used the convenience of cordless power to clean or cut something. Highly recommended - with a big battery pack. It needs some serious juice.

This is an excellent hand-held grinder. Small and light weight but able to able the bigger jobs. Very easy to use.

Been using tool for over 4 months with no problems. Use mostly for cut off wheel. Long run time with 4 ah battery. Good power for cordless tool.

Has plenty of power. Runs until battery is almost fully depleted before slowing.

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 bought this last October and have used it a number of times. Most recently this summer I used it to cut rebar sticking up thru a beach from an old break wall.

Old 18v quit so we upgraded to this and just incredible how much nicer it is. Smooth start and the switch works great. Another top notch addition to the tools

very happy. Dont use electric any more. power to spare.

My son gave this to me as Father's Day present; thought it would be an OK item in workshop. Now, I seem to carry it in my vehicle to all rentals, as the need for something 'quick & easy' happens often during repairs. Always carry a small pack of extra wheels, but never an extra battery, which is great!
