Gator 3073 Fiber Disc 36 Grit 4.5 in Angle Grinder 3 Pack

Product Description

The GATOR 3073 is a heavy-duty aluminum oxide resin fiber disc designed for aggressive material removal and general-purpose surface work. At 4.5 inches in diameter with a 36-grit abrasive, this disc cuts fast and handles demanding applications without loading up quickly. Sold in a 3-pack, the 3073 mounts to a compatible backer pad on a standard angle grinder. Licensed trades and experienced DIYers use these discs for light stock removal, surface cleaning, weld blending, and preparation work before finishing coats. Aluminum oxide construction provides consistent cut rate and durability across a range of ferrous and non-ferrous surfaces.

These fiber discs are suited for use on metal, steel, and general fabrication surfaces in both shop and field environments. Typical applications include deburring, rust removal, surface prep before painting or coating, and finish blending. The 36-grit rating makes this disc appropriate for initial material removal passes rather than fine finishing. A backer pad is required for use on an angle grinder and is sold separately. The 3-pack quantity supports production work or allows multiple grinders to be staged without downtime between disc changes.

Installation Notes

Installation and disc changes must be performed with the angle grinder powered off and unplugged or battery removed. Always inspect the backer pad for wear or damage before mounting a new disc. Ensure the fiber disc is fully seated and secured on the backer pad before operating the grinder. Follow applicable ANSI B7.1 grinding wheel safety standards and the grinder manufacturer's RPM rating to confirm the disc is rated for the tool's maximum speed.
