Arc Abrasives 71-047805 Resin Fiber Disc 60 Grit 25 Pack

Product Description

The ARC ABRASIVES 71-047805 is a 4.5-inch resin fiber disc designed for aggressive material removal on mild steel surfaces. Each disc measures 4.5 inches in diameter with a 0.875-inch arbor hole and is manufactured with self-sharpening abrasive grains that continuously expose fresh cutting edges during use. Rated at 60 grit, these discs offer a balance between fast stock removal and controlled surface finish. Sold in boxes of 25, the 71-047805 provides a cost-effective alternative to full ceramic abrasive discs without sacrificing consistent performance in grinding and blending applications.

These resin fiber discs are suited for use in fabrication shops, maintenance facilities, and light manufacturing environments where grinding and deburring of mild steel is routine. The 4.5-inch diameter fits standard right-angle grinders equipped with a fiber disc backing pad. The 60-grit designation makes these discs appropriate for initial weld seam grinding, rust removal, and surface preparation ahead of coating or finishing operations. Installers and fabricators working with structural steel, sheet metal, and welded assemblies will find these discs a practical choice for day-to-day abrasive tasks.

Installation Notes

Resin fiber discs must be mounted on a proper rigid or semi-rigid backing pad rated for the disc diameter before use on a right-angle grinder. Ensure the grinder is rated for the disc size and that all guards are in place before operation. Inspect each disc for cracks or damage before mounting, and never use a damaged disc. Follow ANSI B7.1 safety requirements for abrasive wheel use, and wear appropriate PPE including eye and face protection.
