Standard Abrasives 530003, A/O Resin Fiber Disc, 4-1/2 in x 7/8 in 36, 7010331425

Heavy-Duty Disc Withstands High Pressure Applications

Our Standard Abrasives Aluminum Oxide Resin Fiber Disc is constructed with a substantial 30 mil fiber backing and resin-bonded abrasive to provide the rigidity and durability needed for heavy stock removal and high-pressure weld leveling. In industrial environments where prolonged use is essential, fiber discs offer great results. Use this economical disc for removing welds and imperfections or blending and finishing larger surface areas.

Fast Cut, Long Life
Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

Using a Fiber Disc
Fiber discs are heavy-duty discs ideal for weld removal, grinding, and blending large and small areas of metal surfaces. They feature a tough, stiff backing made from vulcanized fiber that resists wear and can handle tough grinding applications. Fiber discs with a 7/8″ center hole are mounted onto a right angle grinder. They are secured to a holder pad with a compatible disc retainer nut (both sold separately). For optimal performance, the disc should be used with a holder pad of the appropriate density for the application – a lighter density holder pad for fine grade grinding applications, and a harder density holder pad for coarse grade grinding applications. Using the correct holder pad for the application ensures that the abrasive mineral will continually re-sharpen, maximizing the life of the abrasive.

Our Standard Abrasives Aluminum Oxide Resin Fiber Disc is a good choice for high-pressure applications. This center hole disc comes in coarse grades and is also available in smaller sizes with a quick change attachment (sold separately). For maximum durability and disc performance rate, we recommend a Standard Abrasives Holder Pad for attachment to a right angle grinder.
