Soft flap discs consist of flexible abrasive flaps, most often soft fabric or rubber. Having some flexibility gives the disc the ability to conform to more contoured surfaces which is critical for precision in surface grinding or polishing. In the jewelry line, soft flap discs find application in polishing intricate gemstones as well as the polished metallic settings. In addition, they can be used to sand and finish automotive body curved panels without interruption of contour continuity. Due to the soft nature of the flaps, scratching delicate surfaces is less likely which also improves the design of the flaps.
