Norton 69957370207 Fiber Disc 60 Grit Ceramic Alumina 4.5 in

Product Description

The NORTON 69957370207 is a coated fiber disc designed for aggressive material removal on metal and other hard surfaces. Part of the BlazeX F970 series, it uses a ceramic alumina abrasive grain bonded with a resinoid bond to a fiber backing. The disc measures 4.5 inches in diameter with a 5/8-11 threaded arbor hole for direct mounting to a compatible back-up pad. Rated to 11,000 RPM, it delivers sustained cutting performance in grinding, blending, and surface conditioning applications. This disc is sold individually and requires a minimum order of 25 units.

This disc is suited for angle grinder use in residential, commercial, and light industrial settings. It is designed for use with the Norton Speed-Change Back-Up Pad, which allows fast disc swaps without tools. Typical applications include weld removal, edge grinding, and surface preparation on ferrous and non-ferrous metals. The 60-grit medium grade provides a balance between stock removal rate and surface finish, making it appropriate for general fabrication and maintenance work performed by metal fabricators, pipefitters, ironworkers, and maintenance technicians.

Key Features

• Ceramic alumina abrasive grain for high cut rate and extended disc life
• Resinoid bond holds grain securely under high-load grinding conditions
• Fiber backing provides rigidity and durability during aggressive material removal
• 5/8-11 threaded arbor hole mounts directly to Norton Speed-Change Back-Up Pad
• 11,000 RPM maximum speed rating suitable for standard 4.5-inch angle grinders
• 60-grit medium grade balances stock removal with surface finish quality

Compatibility

Designed for use with the Norton Speed-Change Back-Up Pad. The 5/8-11 threaded arbor hole fits standard angle grinder spindles accepting that thread size.

Installation Notes

Installation is performed by threading the disc directly onto a compatible back-up pad mounted to an angle grinder. Verify the grinder free-speed RPM does not exceed the 11,000 RPM disc rating before operation. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or edge damage. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting and personal protective equipment.
