Brief: Strip Discs are the perfect choice for cleaning and stripping metal surfaces. Simply attach to your angle grinder and these discs allow you to remove scaling, oxidation, or clean up weld lines. These strip discs are extremely versatile and are specially designed to strip quickly with minimal under-material loss. Each Strip Disc is made with a premium purple (extra coarse) nonwoven. Purple webbing is a new and improved webbing material, that offers a longer life. Strip discs are a safer alternative to wire brushes. Strip and Clean discs are great for auto body shops needing to remove paint and undercoating while still protecting the vehicle body.
