Flap Discs

Flap discs combine rapid material removal with the ability to blend and finish surfaces in a single operational step, making them essential for metal fabrication, weld seam blending, and deburring. Built with overlapping abrasive cloth flaps that continuously expose fresh grains as they wear, they deliver consistent cutting action, reduced thermal buildup, and extended working life compared to standard grinding wheels. Available in multiple diameters, backing types, and grain formulations—including aluminum oxide, zirconia alumina, and ceramic—they provide the optimal balance of stock removal, control, and surface finish across carbon steel, stainless steel, and non-ferrous alloys.
