That would be retarded to use on a project inside. Even with a vacuum hookup, the dust would be killer. Think of it the same a grinder with a tile wheel. I have this for my grinder, and use it from time to time to bevel edges, cut circles, you know little stuff. Even doing that, you can destroy your work area in seconds.
You want to cut a line in concrete, just get that blade for your cheap **** skill saw. Thats it.
