Norton 666233-65600 Ceramic Alumina Fiber Disc 80 Grit 25 Pack

Product Description

The NORTON 666233-65600 is a ceramic alumina fiber disc engineered for aggressive material removal and long service life on metal fabrication and surface conditioning applications. Built on the Merit FX965 platform, this disc uses ceramic alumina abrasive grain, which self-sharpens under pressure to maintain a consistent cut rate throughout the disc life. At 7 inches in diameter with a 7/8-inch arbor hole and an 80-grit abrasive rating, it strikes a practical balance between stock removal speed and surface finish quality. Sold in packs of 25, this disc is a standard choice for angle grinder work in metalworking, welding prep, and weld blending.

These fiber discs are suited for use on ferrous metals including steel and cast iron, as well as stainless steel and other hard alloys where conventional aluminum oxide discs wear too quickly. The 80-grit specification makes them appropriate for weld removal, deburring, edge blending, and surface preparation prior to coating or inspection. Fabrication shops, structural steel contractors, shipyards, and industrial maintenance crews routinely use this disc type for high-volume grinding tasks. The 25-unit pack supports professional job-site and shop consumption rates.

Key Features

• Ceramic alumina grain self-sharpens under load for extended disc life and consistent cut rate
• 80 grit delivers fast stock removal with a moderate surface finish suitable for weld blending and prep work
• 7-inch diameter with 7/8-inch arbor hole fits standard right-angle grinders
• Merit FX965 construction provides a rigid fiber backing for stability under pressure
• Sold in a 25-disc pack for shop and production-volume use

Compatibility

Designed for use with standard 7-inch right-angle grinders and disc grinders fitted with a 7/8-inch arbor or appropriate backing pad. Confirm tool RPM rating meets or exceeds the disc maximum RPM before use.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or battery removed. A suitable backing pad rated for fiber disc use is required to support the disc properly during operation. Always verify the tool and disc maximum RPM ratings are compatible before mounting. Personal protective equipment including eye protection and gloves is required; follow applicable ANSI and OSHA abrasive wheel safety standards during use.
