Arc Abrasives 37114 Resin Fiber Disc 80 Grit 4-1/2 in

Product Description

The ARC ABRASIVES 37114 is a resin fiber disc designed for aggressive material removal on steel, aluminum, and other non-ferrous metals. Measuring 4-1/2 inches in diameter with a 7/8-inch arbor hole, this disc uses an 80-grit abrasive grain bonded to a fiber backing with a resin bond system. A built-in grinding aid reduces heat buildup during use, which helps extend disc life and maintain cutting efficiency. Metalworkers, fabricators, and maintenance technicians use this disc with standard angle grinders for weld blending, surface conditioning, and stock removal tasks.

This disc is suited for use on mild steel, stainless steel, aluminum, and general non-ferrous metals in fabrication shops, maintenance facilities, and light industrial environments. The 4-1/2-inch diameter fits the most common angle grinder size used in the trade, and the 7/8-inch arbor is compatible with standard grinder spindles. The 80-grit rating provides a balance between material removal speed and surface finish, making it practical for weld cleanup and surface prep work ahead of coating or inspection.

Compatibility

Designed as an OEM-style replacement resin fiber disc for use with standard 4-1/2-inch angle grinders equipped with a 7/8-inch arbor spindle.

Installation Notes

Resin fiber discs are installed and serviced by metalworkers, fabricators, and maintenance technicians. Before mounting, ensure the angle grinder is disconnected from power. Inspect the disc for cracks or damage before each use and do not use damaged discs. Follow all applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels, and always use the appropriate guard on the grinder.
