Norton 69957370206 Ceramic Alumina Fiber Disc 4-1/2 in 50 Grit

Product Description

The NORTON 69957370206 is a ceramic alumina fiber disc engineered for aggressive material removal on metal, stainless steel, and hard alloys. Part of the BlazeX F970 Series, this 4-1/2 inch disc uses a resinoid bond and fiber backing to deliver consistent cut rates and extended disc life under high-pressure grinding. The ceramic alumina abrasive self-sharpens during use, maintaining cut performance longer than conventional aluminum oxide grains. At 50 grit coarse grade, it is suited for weld blending, stock removal, and surface conditioning. Rated to 11,000 RPM and weighing 0.06 pounds, it is designed for use with a compatible threaded arbor back-up pad.

This disc is used in fabrication shops, structural steel work, and maintenance grinding applications where consistent stock removal is required. The 5/8-11 threaded arbor hole attachment mounts to angle grinders fitted with a Norton Speed-Change Back-Up Pad, enabling fast disc swaps without additional hardware. It is appropriate for both shop and field use by welders, fabricators, and metal finishing technicians working on ferrous and non-ferrous substrates.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety and abrasive product handling. Always verify the grinder RPM rating meets or exceeds the disc maximum of 11,000 RPM before mounting. Power down and disconnect the grinder from its power source before changing discs. Inspect the disc for damage before each use and never exceed the rated speed.
