United Abrasives/SAIT™ fiber discs are made with the highest quality materials using a premium resin over resin construction. This uncompromising pursuit of quality is what makes SAIT™ fiber discs world-renowned. Packaged in a unique bulk spindle that assures that each disc remains perfectly flat. This unique design offers the convenience of easy access and can be tightened to insure that your discs are flat when you need them. 2A fiber discs are for general purpose use. Z fiber discs are used for welds and aggressive stock removal on carbon and stainless steel.
Saitech™ 8S Ceramic fiber discs are made with a high performance, ceramic aluminum oxide grain, closed coat. Closed coat means the abrasive grains are adjacent to each other with no space between. Most applications will benefit from closed coat material because it allows for more material removal.
