3M 7100122779 Hook Loop Disc 1500 Grit 6 in Aluminum Oxide 50pk

Product Description

The 3M 7100122779 is a hook and loop abrasive disc designed for fine surface finishing and preparation work. Part of the 3M 260L Series, this disc uses aluminum oxide abrasive bonded to a polyester film backing, delivering consistent cut and a smooth surface finish. At 1500 grit, it falls in the ultra fine grade range, making it suited for final-stage sanding, light defect removal, and surface refinement before topcoat application. The film backing resists tearing and helps maintain a flat cutting surface across the disc. Vacuum holes are included to support dust extraction during use. Each package contains 50 discs.

This disc is used in automotive refinishing, metal fabrication, and woodworking applications where a controlled, ultra fine finish is required at the final sanding stage. The hook and loop attachment system allows fast disc changes on compatible random orbital and dual-action sanders. At 6 inches in diameter, it fits standard 6-inch hook and loop backing pads. Typical users include autobody technicians, industrial finishers, and woodworking professionals who require repeatable results at the ultra fine stage of a sanding sequence.

Installation Notes

Align the vacuum holes on the disc with the ports on the backing pad before pressing firmly to seat the hook and loop connection. Ensure the sander backing pad is clean and free of debris to maintain proper disc adhesion. Inspect the disc before each use and replace if abrasive is worn, disc is torn, or film backing shows separation. Operate equipment according to the tool manufacturer's rated speed for 6-inch abrasive discs.
