Norton ProSand Multi Air 5 Inch Universal Sanding Discs

Norton ProSand Multi-Air 5" Universal Hook & Loop Sanding Discs have a multi-hole vacuum design that not only cuts faster and lasts longer, it requires fewer disc changes, and its unique, multi-hole pattern provides virtually dust-free sanding.

The premium, high-quality ceramic abrasive offers an exceptional cut on all surfaces. The fiber-reinforced latex/paper backing is strong, tear-resistant, and durable. Norton's patented universal multi-air cyclonic 246-hole pattern allows these discs to be used on any 5-inch random orbital hook and loop sander—even Festool—regardless of hole pattern. The discs last longer due to the unique resin bonding system that secures the abrasive to the fiber-reinforced backing and an anti-clog coating.

Multi-air discs are available in grits ranging from extra coarse to extra fine. Sold in packages of 10 discs.

Even with the best dust free system it is impossible to eliminate 100% of all airborne dust particles while using power sanders. We always recommend safety equipment such as a respirator, safety glasses and gloves when using these products.
