Versatile fleece flap discs. For rust removal/descaling of non-ferrous metals, steel, stainless steel and aluminium. For preparing and re-polishing welds, preparing painted surfaces and polishing stainless steel. Very good adaptability to the workpiece shape due to high flexibility of the fleece slats.
