Alpha® PVA VP polishing disc is a versatile, high-speed, dry polishing system used to polish stainless steel for a semi-mirror finish. Fast working and long lasting, the Alpha® PVA VP polishing disc is easy to use and works well on most common high-speed angle grinders, sanders and polishers. It can be used for other applications such as stone, ceramic, wood and other metals. In addition, it works great for paint, rust and coating removal, as the disc will not clog. The Alpha® PVA VP polishing disc is formulated with a silicon carbide abrasive and a polyvinyl alcohol bond that is color-coded for ease of operation. The discs are available with a straight 7/8” arbor or a 5/8”-11 disposable zinc hub for your convenience.
