Sait-Strip non-woven discs have an arbor hole for easy mounting to the grinder shaft. Constructed of large nylon filament to provide an open, non-loading surface, the discs utilize a coarse silicon carbide grain for rapid removal of surface contaminants while producing fine finishes. Excellent for cleaning welds, removing corrosion, rust, scaling, and for blending. Great for removing paints, varnishes and sealants from difficult-to-reach surfaces. Used for stainless steel, high tensile steel, and ferrous and non-ferrous metals. Package of 5.
