The Norton Blaze Multi-Air Cyclonic 5" 80 Grit sanding disc (sold in boxes of 50) is a premium abrasive designed specifically for hardwood floor sanding using orbital or edger machines equipped with vacuum dust extraction. The discs feature a fiber-reinforced, D-weight latex-saturated backing that offers high tear strength and flexibility, essential for the demands of floor sanding. They also include a water-based, non-pigmented No-Fil coating to resist loading and eliminate color transfer onto light wood floors. The NorGrip hook and loop mounting system ensures secure attachment and quick changes.
