Flap disc is a disc-shaped grinder. It is used widely in removing die marks, projecting parts, welding parts, etc. Super disc is effective for flat and convex parts. In addition, because it is pliable, it must be used with a portable motor tool. Because it maintains high-efficiency, low-noise and low-vibration, it plays an outstanding role as a tool. Furthermore, its high operability produces uniform ground surface. Super disc can be applied to various types of materials but it is particularly effective in grinding flat surface, removing joints, rust and stain, smoothing welding parts and grinding curved surface.
