The Norton Cyclonic series offers you a complete sanding solution that allows you to minimize grinding time and increase efficiency through 4 simple sanding steps. Features and Benefits The upgraded dust extraction technology extracts 25% more dust, and the unique hole pattern increases performance by up to 32% compared to conventional multi-hole sanding discs. The discs provide a narrower sanding as they are flatter and the abrasive surface is additionally increased, allowing for a more consistent and faster cut. Due to Nortons ceramic grit, which is sharper, fresher and more evenly worn, ensures consistent grinding results. The use of Multi-Air Cyclonic is improved throughout the life of the disc. Thanks to the unique hole pattern, Norton Cyclonic improves performance by up to 32% compared to the standard multi-hole sanding discs. Multi-Air Cyclonic has an increase of 25% in dust removal. The new hole setting is created using the same science as cyclone formation to allow for the most powerful air movement. The holes are cut into the disc using the new laser cutting technology and do not pierce, making the discs flatter. This improves dust removal and increases the area of abrasive surfaces to achieve more even scratching and better surface processing throughout the life of the disc.
