Gator 3072 Fiber Disc 4.5 in 50 Grit 3 Pack

Product Description

The GATOR 3072 is a heavy-duty aluminum oxide resin fiber disc designed for use on angle grinders with a compatible backer pad. Measuring 4.5 inches in diameter and rated at 50 grit, these discs deliver aggressive material removal while remaining suitable for surface cleaning, finishing, and general-purpose sanding tasks. The aluminum oxide abrasive construction provides consistent cut performance across a range of materials including metal, wood, and painted surfaces. Each pack contains 3 discs, making it practical for job-site use where disc wear is expected. The pack weighs 0.185 pounds.

These fiber discs are intended for light stock removal, surface preparation, and finishing work on angle grinders. The 50-grit rating makes them well-suited for removing rust, scale, weld spatter, and surface coatings, as well as general deburring and blending work. They are commonly used by metalworkers, fabricators, maintenance technicians, and contractors performing surface prep prior to welding, painting, or coating application. The resin bond construction holds up under the heat and pressure generated during aggressive grinding passes.
