Norton 77696090176 Flap Disc 40 Grit Type 27 2 Inch

Product Description

The NORTON 77696090176 is a Type 27 flap disc engineered for aggressive material removal on metal and fabricated surfaces. Running at a maximum of 30,000 RPM, it carries a coarse 40-grit zirconia alumina abrasive bonded to a durable fiberglass backing. The 2-inch disc attaches via a Quick-Change Type S mount, allowing fast swaps without additional hardware. Zirconia alumina is a self-sharpening abrasive grain well suited to heavy stock removal, weld blending, and surface conditioning on steel and stainless. This disc is designed for use with compatible right-angle die grinders and Quick-Change Type S tool bodies commonly used by metal fabricators, pipefitters, and ironworkers.

This flap disc is used in light fabrication, pipework, and structural metalwork applications where a compact 2-inch tool is required for tight access areas. The Type 27 flat profile keeps the abrasive surface flush to the workpiece, making it appropriate for flat stock, weld seam leveling, and edge work. It is sold individually but requires a minimum order quantity of 10 units, making it a practical stocking item for shops and service trucks.

Installation Notes

Installation is performed by metal fabricators and machinists using compatible Quick-Change Type S grinders. Verify the tool spindle speed meets or exceeds the disc rating before mounting, and never exceed the 30,000 RPM maximum. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always use appropriate eye protection and guarding per ANSI B7.1 and applicable shop safety standards.
