I use a grinder with a wire brush attachment to remove rust and corrosion from many of the projects we all do. It really cant be beat for removing paint, rust, corrosion in a quick manner. Unfortunately the tool has caught my clothing several times wrapping its self to my body, has removed portions of my skin on my hands, caught a wire and flew out of my hands down the driveway in a crazy free spin until I was able to pull the plug..
To protect myself from the flying strains of metal that become detached I wear glasses and overalls and will not use it without heavy gloves ( I have the scars from past times with out them). I'm surprised I haven't been more hurt using this thing, but like I said it does the job...
I just think when it tries to fly out of my hands that its trying to get me..
