Vortex Rapid Finish. Bear-Tex. For surface bettering after grinding with e.g. depressed centre wheels, fibre and flap discs to achieve the final surface finish. Application areas include the removal of sanding scratches, processing surface defects, deburring, rounding, cleaning, corrosion and oxide removal and polishing. It gives an even and smooth surface without burning, and provides fast processing combined with a long life.3AM is softer and flexible, 5AM is harder and is best suited for demanding deburring and rough grinding.The convex form helps to give the right working angle and with that a finer surface and better utilisation of the disc’s full surface.
