Norton 69957370196 Fiber Disc 80 Grit 4.5 Inches

Product Description

The NORTON 69957370196 is a coated fiber disc engineered for aggressive material removal on metal, weld seams, and other hard surfaces. Built on a resinoid bond with a fiber backing, it uses a ceramic alumina abrasive grain rated at 80 grit for medium-grade cutting action. The disc measures 4.5 inches in diameter with a 7/8-inch arbor hole, and is rated to a maximum of 11,000 RPM. Weighing 0.04 pounds per disc, it is designed for use on right-angle grinders fitted with a compatible backing pad. Part of the F970 Series BlazeX line, this disc is a shop-ready consumable for fabrication and maintenance professionals.

This disc is suited for grinding and blending tasks in metal fabrication, welding shops, and general maintenance environments. The 4.5-inch diameter and 7/8-inch arbor hole fit standard right-angle grinder configurations commonly used by pipefitters, ironworkers, and HVAC sheet metal technicians. The ceramic alumina grain is well matched to carbon steel, stainless steel, and similar hard materials where heat generation and disc loading are common concerns.

Installation Notes

Installation should be performed by trained grinding equipment operators following ANSI B7 safety standards and the grinder manufacturer guidelines. Always verify the grinder's rated RPM does not exceed 11,000 RPM before mounting the disc. Inspect the disc for cracks or damage before each use and never use a damaged disc. Use the correct backing pad size and type for this disc diameter and arbor configuration.
