Arc Abrasives 71-047806 Resin Fiber Disc 80 Grit 25 Pack

Product Description

The ARC ABRASIVES 71-047806 is a resin fiber disc engineered for grinding and surface conditioning on mild steel. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, this disc runs at 80 grit and features self-sharpening abrasive grains that maintain cutting performance throughout the life of the disc. Sold in boxes of 25, the 71-047806 is positioned as a cost-effective alternative to full ceramic abrasive discs while still delivering consistent material removal on ferrous metals. It is a standard tool for metalworkers, fabricators, and maintenance technicians who need dependable stock removal without the cost premium of ceramic grain products.

This disc is suited for use on mild steel in light fabrication, weld blending, and general surface prep applications. The 4.5-inch format fits standard right-angle grinders equipped with a fiber disc backing pad and a 0.875-inch arbor. It is commonly used in metal shops, HVAC duct fabrication, and field maintenance work where frequent disc changes and consistent cut rate matter. The 25-unit pack size supports production environments and regular service schedules.
