Resin Fiber Discs are manufactured using a multi-layer, heavy duty vulcanized fiber as backing, which is then covered with a resin bond maker coat specifically designed to resist loading, glazing and grain stripping. This bond coat is then covered with abrasive grains formulated for toughness, sharpness and other particular attributes, according to the area of application. Grains are covered on top with size coat and in many cases there is additive top size coat applied with specific qualities as self-cleaning, lubrication, cooling etc.
Aluminum Oxide Fiber Discs deliver very good cutting rates and offer a longer work life. These discs provide optimal value when used in high stock removal applications and where cool cutting action is required.
Zirconium Sanding Discs self-sharpen while in use, delivering ever-appearing new cutting edges and long useful life for most of the grain layer. This grain structure extends disc life by minimizing grain shedding, while promoting a cool grinding action and reducing glazing and clogging. Well suited for metal, ferrous alloys, harder metal alloys, stainless steel, fiberglass and wood.
Ceramic Sanding Discs are great for applications where heat is a problem. The grains stay sharp as they fracture, because new cutting edges are continually exposed. Ceramic fiber discs outlast other discs on carbon steel. They are longest lasting, most aggressive and with highest stock removal.
Fiber Discs made from Compactgrain, VSM – Made in Germany are among most productive and longest lasting fiber discs with nearly constant stock removal ability due to specific design of grains, formed as granulate where each grains appears as a granule of multitude of smaller abrasive grains. When top grains wear they fall off, letting out fresh sharp edge of a new grain in granule.
Silicon Carbide Sanding Discs due to higher hardness of SiC grains are often designed for construction applications: stone, hard ceramic and terracotta tiles, other ceramic and non-ferrous metal stock removal.
