Arc Abrasives 71-077805 Resin Fiber Disc 60 Grit 25 Pack

Product Description

The ARC ABRASIVES 71-077805 is a resin fiber disc designed for grinding and surface conditioning on mild steel. Measuring 7 inches in diameter with a 7/8-inch arbor hole, this disc uses self-sharpening abrasive grains at 60 grit to maintain consistent cutting action throughout the life of the disc. Sold in a box of 25, it offers a cost-effective alternative to full ceramic abrasive discs while still delivering reliable stock removal. It is suited for use with standard angle grinders and backing pads in fabrication, weld blending, and general metal prep applications.

This disc is intended for use on mild steel surfaces in fabrication shops, job sites, and maintenance environments. The 60 grit designation makes it appropriate for moderate stock removal and weld seam blending rather than fine finishing work. Its self-sharpening grain structure helps extend usable disc life, reducing changeover frequency during production or repair work. Trade professionals including metalworkers, welders, and maintenance technicians will find the 25-disc box quantity practical for ongoing work.

Installation Notes

Resin fiber discs require a compatible rigid or semi-flexible backing pad mounted to an angle grinder rated for the disc diameter and operating speed. Always verify that the grinder RPM rating meets or exceeds the disc RPM rating before use. Wear appropriate PPE including a face shield, gloves, and hearing protection during grinding operations. Inspect each disc for cracks or damage before mounting and do not use damaged discs.
