Norton 076607-03211 Merit Flap Disc 40 Grit 4.5 Inches

Product Description

The NORTON 076607-03211 is a Merit series R822 Charger Jumbo flap disc designed for aggressive material removal on metal surfaces. Built around zirconia alumina abrasive grain, the R822 Charger Jumbo construction delivers consistent cut rates and long service life under heavy grinding loads. At 4.5 inches in diameter with a 5/8-11 threaded hub, it mounts directly to standard right-angle grinders without adapters. The 40-grit designation makes it suited for weld blending, stock removal, and surface conditioning where fast cutting action is the priority. At 2.07 pounds, the disc carries solid mass for a tool of its class. Metal fabricators, ironworkers, and pipefitters are the primary installers and users of this abrasive.

This flap disc is intended for use on ferrous metals, structural steel, and weld joints in both shop and field environments. The 5/8-11 arbor is the standard thread for 4.5-inch angle grinders widely used in fabrication shops, construction sites, and maintenance applications. The 40-grit cut level fits rough grinding passes ahead of finer finishing steps. Minimum order quantity is 5 discs per purchase.

Installation Notes

Flap discs are installed and operated by metal fabricators, welders, and maintenance trades using angle grinders rated for the disc diameter and RPM. Always verify the grinder maximum RPM rating meets or exceeds the disc rated speed before mounting. Inspect the disc for damage before each use and discard any disc that shows delamination or cracking. Wear appropriate PPE including face shield, gloves, and hearing protection during operation.
