Norton 05539510702 Fiber Disc 9.125in 24 Grit Merit FX370

Product Description

The NORTON 05539510702 is an aluminum oxide fiber disc designed for aggressive material removal on metal, weld seams, and other hard surfaces. Built on the Merit FX370 fiber backing, this 9.125-inch diameter disc delivers consistent cut rate and edge durability under heavy grinding loads. At 24 grit, it is suited for rapid stock removal, deburring, and surface prep work where a coarser scratch pattern is acceptable before finishing passes. Licensed trades and fabrication shops rely on this disc for use with right-angle grinders equipped with a backing pad. The bulk pack of 25 discs keeps job sites stocked without interruption.

This disc is used in industrial and commercial fabrication environments as well as field metalworking applications. Common tasks include weld grinding, rust removal, scale removal, and edge chamfering on structural steel, plate stock, and pipe. The 7/8-inch arbor hole fits standard right-angle grinder mandrels and backing pads. It is appropriate for use by ironworkers, pipefitters, welders, and maintenance trades working on ferrous metals and similar hard materials.

Compatibility

Installation Notes

Fiber discs must be mounted on a rigid or semi-flexible backing pad rated for the disc diameter before use on a right-angle grinder. Always power down and disconnect the grinder before changing discs. Inspect the disc for cracks, tears, or delamination prior to each use and discard any damaged disc immediately. Follow all applicable ANSI B7.1 safety standards for abrasive wheel mounting and operation, and wear appropriate PPE including a face shield and gloves during grinding operations.
