Norton 076607-03213 Norzon 20X Flap Disc 80 Grit 5 Pack

Product Description

The NORTON 076607-03213 is a Norzon 20X flap disc engineered for aggressive material removal and extended service life on angle grinders. Measuring 4.5 inches in diameter with a 5/8-11 threaded hub, this disc mounts directly to standard angle grinders without an adapter. The 80-grit abrasive delivers a balance of cut rate and surface finish suitable for weld blending, deburring, and stock removal on ferrous and non-ferrous metals. Norzon 20X grain technology is engineered to fracture during use, continuously exposing fresh cutting edges to maintain consistent performance throughout the life of the disc.

These flap discs are used by metalworkers, fabricators, pipefitters, and maintenance technicians in both shop and field environments. Typical applications include weld seam removal, edge chamfering, surface prep before coating or painting, and rust or scale removal on structural steel, pipe, and plate. The 5/8-11 hub threads directly onto angle grinders in the 4.5-inch class, which are among the most common tools in fabrication and maintenance settings. Each purchase includes a pack of 5 discs.

Key Features

Compatibility

Designed for use on 4.5-inch angle grinders equipped with a 5/8-11 spindle thread, which is the standard spindle size for this grinder class across most major tool brands.

Installation Notes

Flap disc installation and use should be performed by operators familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Confirm the disc's rated RPM meets or exceeds the grinder's no-load RPM before operation, and ensure the 5/8-11 hub is fully threaded and secure before applying load. Wear appropriate PPE including a face shield, gloves, and hearing protection during grinding operations.
