Angle Grinder - Cordless - 4 1/2" - 20 V is rated 4.6 out of 5 by 75.
Rated 5 out of 5 by from Amazing Product I bought this grinder just to add it to my tools but end up using it several times during a remodeling and I must say for a battery operated tool it works perfect.

Rated 4 out of 5 by from love & hate it love dewalt tool's they never let me down. but they are going away from hard case's to bag's. these soft bag's do not protect my investment. if they continue doing so I may have to switch brands. I work hard for my money.

Rated 5 out of 5 by from Awesome Grinder Very powerful grinder, easy to change discs and easy to handle. Tons of power and will make quick work of most metals. It comes with a grinding wheel so its pretty much ready to go out of the box (if you have battery packs).

Rated 5 out of 5 by from Best Value I use my grinder for cutting cast iron pipes, unistrut, you name it and I have had little to no problems. I really enjoy the ergonomic feel and the hand guard. I had the xr grinder but I returned it and got this one just for the guard. Only thing is it will eat a 2ah battery in 30 minutes of use, which isn’t bad at all for a cordless machine that can cut through steel like butter but not ideal for a full work day. However if you get yourself a pair of 6ah batteries you’ll bet set to cut through a tank. Anyway great tool, Thanks Dewalt

Rated 2 out of 5 by from Wheres the wheel wrench ? Wheres the wheel wrench ? This is the second unit without the tightening wrench. I have an allen key which goes in nothing . The holes on the wheel chuck are there for the wrench . I love Dewalt and have 3 impact drivers , 3 drills ,2 sawzalls and 2 dewalt weed trimmers . This will be going back to lowes .

Rated 4 out of 5 by from Multiple uses! I have had this grinder for a few months now. The blades are easy to switch out. The grinder itself is easy to use. You are able to move the guard plate To whatever position you need it for. I’ve used it to grind off nails, cut porcelain and ceramic tiles, even smooth out concrete surfaces. This grinder has multiple uses. Just be sure to get the proper blade for your project. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Always close at hand I added this to my Dewalt tool list and it was the best thing I ever did. Working in my garage this grinder always has a cutoff wheel on it. Zip your done. What hacksaw, its in its place in the tool box. This is the best way to go.

Rated 5 out of 5 by from Great Compliment to my collection of 20V Dewalts' Definitely a durable and reliable tool. Using as both a grinder and a cutting wheel. I bought the separate guard for the cutting wheel. Don't need to, if you get the T25 wheels.(with the offset) But I got the flat cutting wheels in bulk. I also have one of the longer lasting batteries. (4.0Ah) The quality of cutting wheels do make a difference, so shop around. This tool does everything I ask. I would even consider getting a second one, and use one for a grinder and the other for a cutting tool.

Rated 5 out of 5 by from DeWalt Angle Grinder I didnt really know whether to get the grinder that runs at 7000 or 9000 rpms. This grinder did great at 7000 rpms. I used it to cut a fence post and grind a Ballard. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from handy on the farm Bought this tool and use it in my mobile repair shop, I use exclusively cordless tools as i rarely have AC power. I use 4ah batteries and have had no issues.

Rated 5 out of 5 by from Dewalt Angle Grinder gets the job done Great tool for the price! Keep in mind it's cordless so of course it won't be as powerful as a corded version. Also it doesn't come with a battery. And it doesn't come with a hard case, but you clearly know that prior to purchase so I don't know how people can deduct for that. If you have plenty of 20-V batteries and you have a use for this tool, it's an excellent addition to your tool collection. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Good for light work Had this grinder for a while now. Have done both light and heavy grinding (not a lot of heavy grinding due to its efficiency) but a lot of light work. Smaller tasks that dragging a cord out wouldn’t be worth your time. Not the most efficient model due to it not being brushless but, it a base model. Also likes to get a little warm after a while. Overall I’m pretty satisfied for what I paid for it. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great value for the DIY-er I bought this after finding the need to cut through some metal at the house. It worked for its intended purpose perfectly but i find myself reaching for it for more and more uses. It has come in handy multiple times and has way tons more uses than originally thought. I've ground concrete down with this, i've cut metal, i've sanded wood even. Super useful tool to have around the house! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great portable grinder/cutter I have a Dewalt cordless drill that has worked great so added this grinder. Have a small ranch with a lot of pipe fencing and other 'remote' things that need repairing and these cordless tools are great for that - saves hooking up trailer and generator to get some 'easy' fixes done. Also got in during the great deal of 'free' battery and charger but it works with my drill batts too. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from LOCK feature Recently just bought this grinder and I love it. I have the cord grinder but I have always wanted a cordless grinder for when I need it when there is no outlet near by or if I’m to lazy to plug in my other grinder. Very portable and easy to use. I love the locking feature makes it safe to change discs. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Handy as a shirt Pocket! I’ve had this grinder for a couple years and it is far and away the most versatile addition to my 20v Max collection. I use it often with a cut off wheel and it works fantastic! The battery life will surprise you and it has more power than a typical corded grinder. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from 4.5" 20 volt Dewalt Grinder The grinder has all the power needed to dress up my welding jobs and other odd jobs I've done. My only complaint is Dewalt furnishes a hex key to change the wheel but does NOT cut a hole in the handle with a rubber grommet to be able to keep up with the hex key. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great tool! Purchased this because I’ve needed one that was more versatile than a corded one. This works flawlessly, and not having to drag a cord out and around everytime, made it worth it alone. Has a good solid feel, as do all the newer Dewalt tools. Great all around grinder/cut off tool. Two thumbs up.

Rated 4 out of 5 by from Great tool! Only grief is the 3.0A batteries do not last very long. It makes sense, I just wished this was more evident when I purchased it instead of the usual “it works with 20v Max batteries!”. Ultimately I had buy a new battery, and opted for the FlexVolt. Wonderful mix!!!

Rated 5 out of 5 by from Nothing surprising about this gem I have acquired several Dewalt 20V Max tools and wanted to add this to my arsenal. It works as I expected it would, is built well and fits very well in my hands. I appreciate that the handle of the tool is large enough that the user is able to get a grip on it.
