Norton 69957398013 Fiber Disc 7 in 60 Grit Ceramic

Product Description

The NORTON 69957398013 is a 7-inch ceramic alumina fiber disc engineered for aggressive material removal on metal, weld seams, and other hard surfaces. Part of the R980 series, it carries a 60-grit medium grade rating and uses a resinoid bond over a fiber backing for durability under high-load grinding conditions. The arbor hole attachment mounts directly to angle grinders and disc grinders equipped with a 7/8-inch arbor. With a maximum rated speed of 8,600 RPM, this disc handles the demands of fabrication shops, pipe welding, and structural steel work where consistent cut rate and disc life matter.

This disc is suited for professional metalworking applications including weld blending, surface conditioning, and stock removal on ferrous and non-ferrous materials. Its orange-colored ceramic alumina grain self-sharpens during use, maintaining cut rate longer than conventional aluminum oxide discs. Typical users include metal fabricators, pipe fitters, ironworkers, and maintenance welders working in industrial or heavy commercial environments.

Key Features

• Ceramic alumina abrasive grain for extended disc life and consistent cut rate
• 60-grit medium grade for balanced stock removal and surface finish
• Resinoid bond provides strength and heat resistance under load
• Fiber backing withstands flex and pressure during grinding
• 7/8-inch arbor hole for standard angle grinder compatibility
• 8,600 RPM maximum speed rating

Compatibility

Designed as a direct-mount replacement fiber disc for angle grinders and disc grinders fitted with a 7/8-inch arbor and accepting 7-inch discs.

Installation Notes

Installation and use should be performed by operators familiar with angle grinder safety practices. Always confirm the grinder speed rating meets or does not exceed the 8,600 RPM maximum disc rating before mounting. Inspect the disc for cracks or damage before each use and never operate with a damaged disc. Wear appropriate PPE including a face shield, grinding gloves, and hearing protection during operation.
