Norton 290006M120 Multi-Air Cyclonic Grip-On Sanding Disc - pack of 50

Using the latest manufacturing technology, Norton has developed the most advanced abrasive disc on the market which is called the 'Next Generation Design' of abrasive with a natural progression in dust extraction technology. A perfect combination of abrasive grain innovation, design technology and specialized laser cutting for maximum productivity. The Multi-Air Cyclonic disc has 346 holes in a 6" disc that are precisely cut by a laser. Unlike a die-punched hole which causes deformation at the hole where dust can collect, thereby reducing the cut and the ability to extract dust, the precision laser cut holes are true and flat and aid in directing dust into the holes to reduce contamination in the shop. Multi-Air Cyclonic discs can attach to any multi-hole (54+ holes) back up pad since the holes in the disc do not have to be matched up with the holes in the pad, so changeover is fast and easy. This ingenious hole pattern was inspired by Mother Nature, developed by R&D specialists and can be explained using the Golden Ratio.
