Answer

Hello, we are sorry for any inconvenience. For model DW831 you can use Type 27 Guard and Type 27 Depressed center wheels. type 27 hubbed wheels, 3" wire cup brush, 4" wire wheel , none-hubbed sanding flap disc and hubbed sanding disc.

what volt is this? I have a 220 volt outlet. can I use this?

Answers

No. This is a 120 volt tool. Plugging it into a 220 volt plug could damage the tool. If that is the only plug that you have i would advise that you have this outlet checked by a qualified electrician and re-wire and properly replace this outlet/wiring as needed.

Powerful and Durable Tool
I use this tool in my hardwood floor installation career for several years. I grind concrete, plywood and even cork flooring. This tool has a very powerful motor. After intensive exploitation I change it every two years. Very good quality for less money! Highly recommend!

seems solid.....
just bought this to work on various jobs and no disk with it....no big deal, will throw it into the fire and see how it does......

works great
I used this thing for several years now and have never had a problem with it. It would be nice if "soft start" grinders would be available since it does give a bit of a kick starting up. I would have given it a 5 out of 5 but since they have their own proprietary set up, I've had to buy adaptors to use discs that are not available in the Dewalt line-up.
