A Must Have Tool
The Dewalt DCG413B 4.5 in. Angle Grinder is an excellent upgrade from my Porter Cable grinder. I've been a Porter Cable tool guy for years, but they do not make upgrades in their tools like Dewalt does.

This tool works great, and has plenty of power without stalling. I tried it out today, and was surprised at how well it cut through steel tubing with no problem.

This was my last addition to my new set. I now have a complete Dewalt 20v XR tool set including drill/ impact, circular saw, flashlights, extra batteries and chargers, and finally this angle grinder. If you're still deciding, this is the one to buy. And CPO was great with fast free delivery. And Thanks CPO for the Free Dewalt 20v 5ah battery included with this angle grinder.

This complete set is a Christmas present to myself, and all at a great deal.

Great run time on battery
I am a welder by trade and have used this grinder daily on metal and have also done concrete grinding to level floor for tile . This grinder is super lightweight and comfortable to use

Perfect balance
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.

Very convenient tool, but blows through batteries
Like this a lot more than the corded angle grinders since you aren’t tied to a wall or extension cord, but you better make sure you have a lot of charged batteries because it blows through them like they’re nothing.

Have always been been leary of cordless grinders, but this one blew away my expectations! So much power and far smoother than the corded version. As a tile contractor I use it daily for countless tasks, and am so glad for another beauty from Dewalt!

DeWalt Quality
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.

I bought this because my old grinder was over 20 years old and I needed to cut off a lot of nails from scrap wood. I am so happy with this. I had no idea how good the battery powered tools have gotten. I will be buying more and am excited about the flexvolt line.

This was a great grinder that I used sparingly. In less then six months it is no longer working. I’m not sure if I would buy another brushless grinder as there is now way to work on them. This isn’t a knock against Dewalt as every cordless power tool I own is from them.

What kind of battery life can I expect?
A shopper on Jan 14, 2018
BEST ANSWER: Short with the standard 20 volt battery. I have used 1.5ah & 2ah batteries and it dies after a few minutes of continuous use.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
