3M 7100074464 Hook Loop Abrasive Disc 5 in Aluminum Oxide

Product Description

The 3M 7100074464 is a 5-inch hook and loop non-woven abrasive disc designed for surface conditioning, finishing, and blending applications. Built on a flexible non-woven construction with aluminum oxide abrasive, this disc delivers consistent cut and finish on metal, painted surfaces, and composite materials. It mounts via a hook and loop backing for fast disc changes without adhesives. Rated to a maximum of 12,000 RPM, it suits both right-angle grinders and random orbital sanders used in light fabrication, maintenance, and surface prep work. The maroon color indicates a Very Fine grade, appropriate for fine finishing and light deburring passes.

This disc is used in residential and commercial settings wherever surface conditioning or fine abrasive finishing is required. Typical applications include weld blending, light rust removal, paint scuffing before refinishing, and surface prep on stainless steel, aluminum, and mild steel. The flexible backing conforms to contoured surfaces, making it effective on irregular geometries that rigid discs cannot reach cleanly. It is commonly installed by maintenance technicians, metal fabricators, and general tradespeople working with portable angle grinders or orbital finishing tools.

Installation Notes

Ensure the tool is powered off and unplugged before mounting or removing the disc. Verify the tool's maximum RPM rating meets or exceeds the disc's rated speed before operation. Align the hook and loop backing pad carefully before pressing the disc into place to ensure full contact and secure seating. Inspect the disc and backing pad for wear or damage before each use and replace if fraying, tearing, or delamination is present.
