Excellent grinder
I've used this grinder to get into tight spots on cast parts, it works great. It doesn't bog down, the built in LED lights help a ton. The tool itself feels good to use and the variable speed trigger works good. It doesn't go through batteries extremely quickly but it's good to have one ready incase the one you're using gets low. Dust and dirt hasn't even phased the grinder, I suspect it'll be with me for many more years. Not a tool you need everyday but when you need one they're indispensable.

Essentially a huge Dremel tool. And I like it.
When I first got this as a woodworker I wondered what i would use it for. A Dremel is useful for delicate things, but this is a much bigger and powerful tool than that. Paired with a flap disk its really nice for shaping wood in a quick fashion. If your a metal worker, this is extremely useful for cleaning welds and metal shavings. After holding and using this tool, you can tell it will last a really long time because of its quality construction. If you need something like this, you can't go wrong.

Very Handy!
So far this has become a valuable staple in the truck. I’ve used it multiple times since acquiring and surprisingly for more things than I originally thought I would. For example: used the flap wheel on some old door hardware (shines up beautifully, the grinder is great for tweaking door strikes, a quick sanding on some hard to reach areas of a stairwell, putting a quick blade edge on my handy machete, etc. So far this has become a great tool. Can’t wait to see where I’ll be using next. Ample power and great control. The 20v line is the BEST line of cordless tools available. Adding items as we can afford and not one item has failed to impress the whole crew.

Best tool ever
Received this tool about two weeks ago and literally every guy on my team used it and fell in love. Basically wanted to fight over who had the chance to use it that day. Batteries held strong and now my boss is trying to steal it from me. Not today buddy. This is diff a keeper would recommend it for basically everything. Keep up the great work!!!!

Variable speed and ease of use.
I received this just in time to assist me with a bathroom remodel. With the 80 grit flap wheel It easily removed construction adhesive and leftover Sheetrock from studs as well as grinding down leftover trim nails at the same time. It saved me a ton of time not having to use a hammer and chisel. I also used it to grind off the slag and surface rust from my welding table, and it still has some meat left on the bone. The variable speed was a nice feature that gives you extra power or helps you not burn the surface your working on.
The trigger is hard to squeeze, expect hand fatigue if you are using it for an extended duration.
The chuck requires the use of two wrenches that are supplied to, but it would be nice to see some sort of keyless chuck added.
Overall it’s a great tool and will make jobs easier on me.

Countless uses - great power, heavy duty
Built like a tank, like most Dewalt products. This is definitely a contractor-grade build. The hand-hold on the front makes it easy to lean a shoulder or hip against a table or surface and keep the die grinder very steady. It's not quite balanced right for one-handed operation where you need quick, fine movements - you really need a more compact design for that - but works well for most things. Does a good job engaging wood, metal, fiberglass, etc.
The trigger is locked out unless you hold the lock off - this is a little bit annoying, but fairly easy to get the hang of.
The kit is great - TWO 20V XR batteries and a charger. The die grinder definitely can make use of both batteries, but isn't as much of a power hog as I was expecting.
The speed range switch on the 'foot' is a great feature that gives you maximum control - it allows you to set the range you would like to work in, which is especially useful when you don't want to accidentally spin up a tool to 25k RPM for safety reasons.

Tough and versatile
This grinder kit does it all. It came with two batteries and the charger. The grinder itself was easy to use and simple to operate. The batteries lasted an extra long time and I was very happy with the charging rate. The workers were all trying to get this baby because it was so easy to use and comfortable to hold. Thank you for making this grinders top of the line tool.
