Norton 69957370203 Ceramic Alumina Fiber Disc 7in 60G

Product Description

The NORTON 69957370203 is a 7-inch ceramic alumina fiber disc designed for aggressive material removal on metal surfaces. Built on a resinoid-bonded fiber backing, this coated abrasive disc operates at up to 8600 RPM and delivers consistent cut rates on steel, stainless steel, and other hard metals. The ceramic alumina grain self-sharpens during use, maintaining cutting efficiency longer than standard aluminum oxide alternatives. At 60 grit, this disc is suited for medium-grade stock removal, weld blending, and surface conditioning tasks common in fabrication and maintenance applications. It is installed via a 7/8-inch arbor hole and weighs 0.12 pounds per disc.

This fiber disc is used in metal fabrication shops, structural steel work, and field maintenance environments where angle grinders are the primary tool. The 7-inch diameter is common on larger angle grinders and right-angle grinders used by ironworkers, pipefitters, and millwrights. At 60 grit, it handles weld seam blending, rust removal, and surface prep ahead of coating or inspection. It is sold individually but requires a minimum order quantity of 25 units, making it appropriate for shop stock or contractor supply orders rather than single-unit purchases.

Key Features

• Ceramic alumina abrasive grain self-sharpens for extended disc life on hard metals
• 60 grit medium grade suited for stock removal, weld blending, and surface prep
• Resinoid bond provides durability under high-pressure grinding conditions
• Rated to 8600 RPM maximum operating speed
• 7/8-inch arbor hole attachment compatible with standard angle grinder arbors
• Fiber backing resists flex and maintains disc integrity during aggressive use

Compatibility

Designed for use with 7-inch angle grinders and right-angle grinders equipped with a 7/8-inch arbor. Verify that the grinder speed rating does not exceed 8600 RPM before mounting this disc.

Installation Notes

Installation and use of grinding discs should be performed by qualified trade personnel familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Confirm the grinder free-speed rating does not exceed the disc maximum of 8600 RPM. Use the appropriate backing pad and flange hardware for 7-inch fiber discs, and inspect the disc for damage before each use. ANSI B7.1 and applicable OSHA standards govern abrasive wheel mounting and operation.
