Norton 69957370209 Ceramic Alumina Fiber Disc 5 in 36 Grit

Product Description

The NORTON 69957370209 is a ceramic alumina coated fiber disc designed for aggressive material removal on metal, weld seams, and hard-to-grind surfaces. Built on a resinoid bond with a rigid fiber backing, this disc operates at up to 10,000 RPM and delivers the cutting action expected from a very coarse 36-grit abrasive. The orange disc measures 5 inches in diameter with a 5/8-11 threaded arbor hole for direct mounting to a compatible back-up pad. It is part of the Norton BlazeX F970 series, engineered for extended life and consistent stock removal in heavy-duty grinding applications. Licensed tradespeople working fabrication, maintenance, or structural steel applications will find this disc suited to demanding workloads.

This fiber disc is intended for use in industrial and commercial grinding tasks where high material removal rates are required. Typical applications include weld blending, surface conditioning, and deburring on carbon steel, stainless steel, and cast iron. The 5/8-11 threaded attachment is compatible with the Norton Speed-Change Back-Up Pad system, making disc swaps faster during multi-pass grinding work. It is sold individually but requires a minimum order of 25 units per purchase.

Installation Notes

This disc is installed by a threaded arbor connection and must be mounted to a compatible back-up pad rated for the grinder in use. Before mounting or removing the disc, disconnect power to the angle grinder and allow any residual rotation to stop completely. Verify that the grinder's rated no-load RPM does not exceed the 10,000 RPM disc rating before operation. Inspect the disc for damage before each use and do not use a disc that shows cracking, tears, or missing segments.
