Norton 77696090168 Flap Disc 80 Grit Type 27 2 Inch

Product Description

The NORTON 77696090168 is a Type 27 coated flap disc designed for aggressive stock removal and blending on metal surfaces. Built with zirconia alumina abrasive at 80 grit (medium grade), it delivers consistent cut rate and durability across grinding and finishing passes. The fiberglass backing provides rigidity and resistance to flex under load. A Quick-Change Type R attachment allows tool-free disc swaps, reducing downtime during production work. Rated to 30,000 RPM, this disc is suited for use on high-speed die grinders and right-angle tools common in fabrication and welding environments.

This flap disc is used in metal fabrication, welding prep, and surface conditioning applications. The Type 27 profile — flat face — is standard for blending welds, removing mill scale, and light stock removal on flat and contoured workpieces. The 2-inch diameter and Quick-Change Type R mount make it compatible with compact pneumatic and electric die grinders used by metalworkers, pipefitters, ironworkers, and maintenance technicians working in tight spaces.

Installation Notes

Installation is performed by metalworkers and maintenance trades using compatible Quick-Change Type R mandrels. Verify the tool RPM rating meets or exceeds the disc rating before mounting. Always inspect the disc for damage before use and ensure the guard is in place per ANSI B7.1 and tool manufacturer guidelines. Do not exceed the marked maximum RPM.
