The Norton Abrasives 62328 ceramic grinding disc is built with an engineered double laminate backing that provides exceptional durability for demanding applications. This design prevents frayed edges and eliminates disc failure. The advanced ceramic grain continuously self sharpens, cutting cooler and lasting longer than conventional grinding discs. A quick, tool free disc change system helps reduce downtime and increase productivity. Available in both 2 inch and 3 inch sizes, the disc is ideal for reaching tight or hard to access areas in grinding and finishing tasks.
