As others have experienced, this grinder packs a lot of power, even though its battery powered. im now a believer that battery powered tools are on par with the corded versions. Fits in your hands well and has a nice e-brake. Indexible guard is a great design.

When I have something big to cut this is my go to tool. I am running it with a 6 inch metal cutting blade.

You will think its plugged in!
Lots of power to cut and score concrete, brick, stone, cement board and tile. So many more applications when using the bigger 6" diamond wheel. Most home centers don't sell the 6" diamond blades, so be prepared to order them online.

60 Volt Flex Dewalt Grinder
I am a heavy user of this tool in all sorts of weather and locations. Use it in wet,dry,dirty and u name it areas and absolutely love it. Lots of power and battery last longer then any cordless grinder I have ever used, which is Milwaukee,Bosh,Makita and Hitachi to name a few.

Dewalt flexvolt grinder (bare tool)
This grinder works excellent and has left me with limited negative feedback to comment on. If had to complain about one thing of the grinder it would have to be that it's a bit longer than your average corded grinder due to the battery that extends out at the rear of the tool !!! This has not became a issue with any of my grinding needs at this point!! I can live with the overall length of the grinder...of that's the only trade off I have to sacrifice to have cord free grinding it's a no brainer . Oh ya and the grinder is no slouch!! It lacks nothing in way of power and is more powerful than most corded grinders with the sound level being half as loud as a typical 4-1/2" corded grinder it's considerably less noisy!! I don't think I'll be using a corded grinder unless in a rare case I need to break out the ol Milwaukee 9" for heavy heavy material removal which isn't often. If you already have a flexvolt tool or tools in the flexvolt line and have the batteries then the barefool grinder is of great value and won't disappoint!!! I'm fairly picky and extremely critical when it comes to tools and especially tools I use on a regular basis as I want performance ease of use and convienance followed by heavy duty and reliability and so far I have no complaints!! If I do end up having a issue with it then I'll be updating my review promptly with details. Get one !!!!!! It'll make you grin at first squeeze of the trigger!!!
