Clean welds, remove rust and strip paints, varnish and other coatings with the Kango 115mm 80G Zirconia Flap Disc. It’s engineered from a zirconia alumina grain that has self-sharpening properties and produces an enhanced material removal rate in metal and wood applications. With a 12° convex angle, this Disc generates a high removal rate on weld seams, edges and other small work surfaces. The fan-shaped design generates a uniform scratch pattern. This eliminates the need to rework surfaces.
