Change your sanding belts less often—these belts have a zirconia alumina abrasive that continuously fractures to form new sharp edges. These self-sharpening edges are great for aggressively removing material on steel and wood. Compared to aluminum oxide sanding belts, these belts sand faster and last longer. Water and cutting fluids won’t break down or soften these belts. A cloth backing makes them flexible yet resistant to tearing. Note: click on a part number to view a volume discount (if applicable).
