Norton 69957370214 Fiber Disc 7 in 50 Grit Ceramic Alumina

Product Description

The NORTON 69957370214 is a 7-inch ceramic alumina fiber disc designed for aggressive material removal on metal and other hard surfaces. Part of the BlazeX F970 series, it carries a coarse 50-grit rating and uses a resinoid bond over a fiber backing for durability under heavy grinding loads. The disc mounts via a threaded 5/8-11 arbor hole and is rated to a maximum of 8,600 RPM. It is intended for use with the Norton Speed-Change Back-Up Pad and is installed by metalworkers, fabricators, and maintenance technicians who require consistent, high-rate stock removal.

This disc is suited for weld grinding, surface prep, and deburring on structural steel, stainless steel, and other metals in both shop and field environments. The coarse 50-grit ceramic alumina abrasive cuts faster and stays sharper longer than conventional aluminum oxide, making it appropriate for high-production or demanding repair work where disc longevity matters. It is sold individually, with a minimum order quantity of 25 units per purchase.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety practices.
