I don't know how some of the other reviewers were using this tool, but I also bought a 4" diamond blade (an expensive high-quality one with lots of diamonds) for cutting through stucco siding and concrete slabs---it works terrific! I don't write many glowing reviews, but I can't say enough good things about this tool. It's light weight and it runs a long time on a single battery---longer than my DeWalt 18V cordless reciprocating saw---doing serious damage. I'm glad I bought it and I'm glad it's in my tool kit. The only negative is that it should have a dust collector attachment because this thing kicks up clouds of dust as it devours concrete.

Mine came in a combo kit with other 18v tools. I fully expected to eBay it away as a bare tool.

Surprise! I've used this thing way more often than I expected! Before I could eBay it, I had a use for it. I use it to sharpen shovels and mower blades, and to cut decking bolts. On several occasion, I've used it to cut chain and to cut slots in stripped bolt heads.

This tool probably won't be suitable for all-day grinding, but it's super handy for those one-off uses as a cordless tool. I'm keeping mine!

Anyone thinking that this is the same as a standard Dewalt angle grinder with a 120 volt motor/cord will be disappointed. That said, even with this tools limitations on power, it is very handy to not have to lug out cords to do a small grinding or cutting job. If you have budget for only one grinder - and had some heavy grinding to do - get a corded model, for a second, third + grinder, or for only light work this tool can be really handy.

not real fast or powerfull but for cutting off bolts, cut a hole in sheet metal 32' up in the air it can't be beat

I have a pneumatic cutoff tool similar to this, but it requires time to start the compressor and dryers on the air line, and for the tanks to come to pressure. I always have an 18V XRP battery ready to go so for quick jobs this is much faster.

It features 2 nice removable guards, one partially open, and one fully enclosed, each with quick release removal and installation levers.

The side handle unscrews for convenience

Additionally, if you want to use normal wheels from the welding store, there is a locknut and wrench that come with this - you don't use them with the dewalt wheels but if you have a supply of grinding wheels you will need those parts, so put them together (I bought the tool only which saves quite a bit and did not include a case)

When you first get the dewalt wheels you should do a edge cut and surface grind to balance the wheel - they are not always perfect and you can feel the wobble until they shape up, which doesn't take long.

Altogether the convenience factor of using 18V batteries (it's ready for li-ion btw) instead of my pneumatic system is great. For big projects, I'll have the compressor running anyways so it's a no brainer, but for small work this is a cheap solution to grind, or cut.

This grinder works great, but I only suggest it for when there isn't an outlet near by to plug in a corded one. With a fully charged lithium XRP battery, you get about 4 - 5 minutes of work before the battery dies. After experiencing the limited life of this grinder, I thought about returning it for another corded one, but I have come across some instances where there either wasn't an outlet near by or my extension cords were quite long enough to reach my project. I decided to keep it for just those situations.

A corded one is also rated at a higher amperage, so this is best for light duty projects. I definitely would suggest only having this as an accessory to a corded grinder.

If you already have DeWalt 18v batteries, then adding this tool to your kit is an affordable way to have a great grinder.
The retailer shipped the product quickly and in perfect condition.

Unlike what listed in the description "The DC411B comes with a Type 27 safety guard, Type 1 cutting wheel and safety guard, two matched flanges, wrench, and side handle.", the Type 27 guard is not included. The type 27 is what most people want/need as it does not get into the way when you work. Amazon will only offer a refund. Will not work with manufacturer to get you the missing (listed) accessory. Will not change the product description. Buy only if you are ready sell out more money for the type 27 guard which you will need if you do any serious work.

I have a pretty complete set of the Dewalt 18V tools, and needed a grinder for doing some concrete surfacing in my garage prior to doing an epoxy coating. I also bought a 4 1/2 inch diamond grinding wheel.

The tool has plenty of power when used with the grinding wheel, but will only last about 10 minutes on a fully charged battery. For my occasional usage, this is fine.

This is the handiest tool in my garage. Very pleased with the quality, portability and power of this little guy. Shoulda had one sooner.
