SG Blaze R980P and TwinStar flap discs from Saint-Gobain Abrasives’ Norton brand feature flexible, plastic back plates that can be trimmed back to expose the flaps, increasing product life and reducing materials costs by enabling virtually all of the abrasive material to be consumed.
The R980P discs feature ceramic alumina abrasive grain and an improved grinding aid for longer life on stainless steel, cobalt, chrome, Inconel, titanium and other hard-to-grind materials. Durable, Y-weight polyester flaps also improve product life, grain retention and fray resistance, the company says. The TwinStar discs are designed for light stock removal on mild carbon steel, ferrous metals and cast iron applications, blending and finishing in one application. Discs in both lines are available in 4 ½-, 5- and 7-inch sizes and with hubs ranging from ⅝ to 11 inches for quick disc changes and decreased downtime.
