High-performance flap discs optimized for use on all metals have a zirconia alumina abrasive. Zirconia alumina grains break down frequently to create fresh, sharp edges to cut and finish faster than aluminum oxide. It cuts cooler than aluminum oxide and is often used for high stock removal or under high pressure.

• Premium abrasive cloth that lasts 15 times longer than fiber resin metal sanding discs
• Zirconia grit removes material 3 times fast than fiber resin metal sanding discs
• Designed for grinding angles of 20-25 degrees.
