Norton 69957370199 Fiber Disc 5 in 60 Grit Ceramic Alumina

Product Description

The NORTON 69957370199 is a 5-inch ceramic alumina fiber disc engineered for aggressive material removal on metal, weld seams, and hard surfaces. Running at up to 10,000 RPM on a standard angle grinder or disc sander, this coated abrasive disc uses a resinoid bond over a fiber backing to hold grain during heavy cutting passes. At 60 grit, it falls in the medium-to-coarse range, making it suitable for stock removal, surface prep, and weld blending. The ceramic alumina abrasive fractures during use to continuously expose fresh cutting edges, extending disc life compared to standard aluminum oxide. Licensed trade fabricators, pipe welders, and metalworkers are the primary users.

This disc is suited for grinding and finishing operations on ferrous and non-ferrous metals in fabrication shops, maintenance facilities, and field service environments. The 7/8-inch arbor hole fits standard backing pads common to 5-inch angle grinders and disc sanders. The orange disc color is consistent with the NORTON F970 BlazeX series product line, which is designed for high-pressure grinding applications where cycle time and consumable cost are primary concerns.

Key Features

• Ceramic alumina abrasive provides self-sharpening grain fracture for extended cut life
• 60 grit medium grade balances aggressive stock removal with surface finish
• Resinoid bond over fiber backing withstands high-pressure grinding passes
• Rated to 10,000 RPM for use with standard 5-inch angle grinders
• 7/8-inch arbor hole fits widely available backing pads
• Sold individually; minimum order quantity of 25 units

Compatibility

Designed as an OEM-style replacement fiber disc for use with 5-inch backing pads accepting a 7/8-inch arbor hole attachment, compatible with standard angle grinders and disc sanders configured for 5-inch coated abrasive discs.

Installation Notes

This disc is installed by grinding professionals and metalworkers following standard coated abrasive mounting procedures. Before mounting, confirm the backing pad is rated at or above 10,000 RPM and is free of damage. Always install and tighten the disc per the tool and backing pad manufacturer torque guidance, and verify the guard is in place before operating. Inspect the disc for tears or damage before each use and discard any disc showing visible defects.
