Scotch-Brite Clean and Strip XT Pro Extra Cut is a heavy-duty stripping disc that uses aluminum oxide abrasive mineral incorporated into a green nonwoven nylon web. It quickly removes thick paint, heavy rust, rust pits and corrosion from metal. The aggressive aluminum oxide mineral then scratches and cleans to the bare metal underneath without leaving divots. This means operators can use this metal stripping disc to remove a coating and get it ready for welding or adhesive application with the same disc. The fibers of this clean and strip disc are highly conformable without compromising strength, meaning improved effectiveness on work piece edges. Here's how it works: the aluminum oxide mineral is embedded into the nylon fibers that gradually break down over time to reveal new fibers and fresh mineral – ensuring a consistent cut over the life of the product. The XT Pro Extra Cut Disc is the most aggressive of the XT Pro line, which offers many advantages over previous clean and strip products: low vibration, decreased chunking, low spark, a higher speed rating and longer life. That all adds up to a stripping disc you can spin onto your right angle grinder with confidence.
