Standard Abrasives 530092, Zirconia Resin Fibre Disc, 36, 4-1/2 in x 7/8 in, 7010367990

Versatile Performance
Our Standard Abrasives Zirconia Resin Fiber Disc is a versatile disc for medium pressure applications, such as removing welds and imperfections or blending and finishing larger surface areas. When it comes to removing burrs, imperfections, gates, risers, and parting lines, this zirconia fiber disc offers excellent performance.

Heavy-Duty Disc Stands up to High Pressure
We construct this disc with a substantial 30 mil fiber backing and resin-bonded abrasive to provide the rigidity and durability needed for stock removal and weld leveling. Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure. In industrial environments where prolonged use is essential, fiber discs offer extended performance.

Zirconia Mineral Provides Extra Fast Cut and Versatility
Alumina zirconia fractures frequently to continually produce sharp points and deliver a faster cut-rate than aluminum oxide. A synthetic mineral, it was developed for heavy stock removal and high pressure grinding. It can be used on a variety of metals including ferrous and non-ferrous alloys, stainless steel, aluminum, and cobalt.

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 sander. They are secured to a holder pad with a compatible disc retainer nut (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 Zirconia Resin Fiber Disc is a good choice for medium or 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.
