Die-cast metal body with brushed nickel finish. It looks especially good with chrome fittings. Running at 20,000 RPM will not remove rust. It comes with an assortment. can we call them blades? Actually grinding wheels, sanding discs, etc. I have worked in the automotive industry and have never had an angle grinder, but recently I saw a video on You Tube of my pet and he was using one of them judiciously. After seeing the performance, I was hooked. Be sure to at least use some air tool oil before each use, and for those who are overly cautious, add a few drops and give a squirt before putting it away. I can't find anything about this tool that is made up. Buy two for the price. One for your garage and one for your basement.
