Norton | Saint-Gobain Abrasives expands its Norton Vortex Rapid Prep non-woven flap disc line with the introduction of 2" and 3" “mini” sizes featuring Norton custom Vortex agglomerate grain, which is said to provide a practical solution from roughing to finishing in one operation for difficult-to-reach, uneven areas.

Norton Vortex Rapid Prep flap discs last longer while simultaneously producing significantly increased cutting rates and smear-free finishes, according to the company. Norton Vortex agglomerated grain technology enables the cutting power of a coarser grit while producing a finer finish in one abrasives disc solution.

For maximum operator comfort, the Vortex Rapid Prep flap discs provide forgiveness and reduced vibration on uneven surfaces.

The discs are well-suited for light blending, stripping, edge breaking and surface prep applications in key industries such as metal fabrication and welding, aerospace, transportation, energy and construction. Norton non-woven flap discs feature specialized 3D non-woven abrasive layers. This design promotes uniform finishing with consistently low surface finish Ra. In addition multiple layers of surface conditioning material provide added life, fewer disc changes for better efficiency, as well as reduced vibration. The discs also feature Norton’s Clean Bond resin technology that provides smear-free finishes even on high-nickel-content alloys and reduced loading when cutting aluminum and other softer metals. Norton Vortex Rapid Prep flap discs are well-suited for cleaning, light deburring and processing welded seams on stainless steel.

Norton Vortex Rapid Prep “Type TR” flap discs are offered in 2″ and 3″ sizes and “Type 27” discs are offered in 4-1/2″ × 7/8″ and 4-1/2″ × 5/8″-11 sizes. The full line is available in very fine, fine, medium and coarse grits.
