Gator 3874 Fine Fiber Disc 4.5 in Angle Grinder 2 Pack

Product Description

The GATOR 3874 is a fine fiber disc designed for surface cleaning and preparation work on angle grinders. Measuring 4.5 inches in diameter, each disc mounts to a standard 4.5-inch angle grinder and removes oxidation, light rust, mill scale, and surface contaminants without aggressive material removal. The fiber construction allows the disc to conform slightly to irregular surfaces, making it effective on flat stock, weld seams, and curved workpieces. Sold in a 2-pack, these discs are a practical stock item for contractors, fabricators, and trade professionals who perform frequent surface prep before coating, painting, or finishing operations.

These discs are suited for use on metal, painted surfaces, and other hard materials where cleaning and prep work precedes a finishing step. Typical applications include pre-weld and post-weld cleanup, rust and scale removal, and surface scuffing prior to priming or coating. They are commonly used by ironworkers, pipefitters, sheet metal mechanics, and general contractors working on structural steel, HVAC ductwork, and mechanical equipment enclosures. The 2-pack format is appropriate for job-site use where multiple discs may be consumed in a single work session.
