Excellent for cleaning welds, removing corrosion, rust, scaling, and for blending. Great for removing paints, varnishes and sealants from difficult-to-reach surfaces. Use 3 Sait-Lok backing pad 95168 (medium density) or 95268 (hard density). Used for stainless steel, high tensile steel, and ferrous and non-ferrous metals. Package of 10.
