Resin Fiber Discs are manufactured using a multi-layer, heavy duty vulcanized fiber as backing, which is then covered with a resin bond coat specifically designed to resist loading, glazing and grain stripping. This bond coat is then covered with mineral abrasive grains formulated for toughness and sharpness.
Aluminum Oxide Sanding Discs deliver superior cutting rates and offer a longer useful life. These discs provide optimal value when used in high stock removal applications and where cool cutting action is required. Zirconia Sanding Discs sharpen themselves while in use, delivering outstanding cutting rates and maximum useful life. This advanced bond extends disc life by minimizing grain shedding, while promoting a cool grinding action which reduces glazing and loading. Ceramic Sanding Discs are great for applications where heat is a problem. The grain stays sharp as they fracture, because new cutting edges are continually exposed. Ceramic fiber discs outlast other discs on carbon steel. Silicon Carbide Sanding Discs are designed for stone, terrazzo, ceramic and non-ferrous metal stock removal.
