Arc Abrasives 10826FF Flap Disc 4.5in Type 27 80 Grit

Product Description

The ARC ABRASIVES 10826FF is a Type 27 flap disc designed for general-purpose grinding and blending on a range of common materials. Measuring 4.5 inches in diameter with a 7/8-inch arbor hole, it mounts to standard angle grinders used daily in fabrication shops, job sites, and maintenance environments. The 80-grit abrasive delivers a balance of material removal and surface finish, making it well suited for deburring, weld blending, and surface preparation. Cotton backing reinforces the abrasive flaps, adding structural strength and extending disc life through demanding work cycles. Metalworking professionals and general fabricators will find this disc a reliable choice for repetitive production tasks.

This flap disc is intended for use on mild steel, aluminum, and composite materials. The Type 27 flat profile is the standard configuration for flat-surface grinding and moderate edge work. It is a common specification in sheet metal fabrication, structural steel work, and light manufacturing where consistent, controlled material removal is required. The 80-grit rating positions it as a medium-grit option, appropriate when initial weld spatter removal or surface conditioning is the primary task rather than fine finishing.

Designed as a general-purpose replacement flap disc for standard 4.5-inch angle grinders accepting a 7/8-inch arbor. No specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by metalworkers and fabricators using a standard angle grinder. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Power down and disconnect the grinder from its power source before changing discs. Inspect the disc for damage before each use and never use a disc that shows cracking, delamination, or missing flaps.
