3M 7000046226 Hook Loop Disc 300 Grit 5 in Aluminum Oxide

Product Description

The 3M 7000046226 is a 5-inch hook and loop abrasive disc designed for finish sanding and surface preparation tasks. Built on a coated aluminum oxide construction, this disc delivers consistent 300-grit extra fine cutting action on wood, painted surfaces, and light metal work. The flexible backing allows the disc to conform to contoured surfaces, improving contact and reducing swirl marks. It mounts to any compatible 5-inch hook and loop backup pad, making disc changes fast without tools. Installers, finish carpenters, and surface prep technicians will find this disc well suited for final passes before coating or inspection.

This disc is appropriate for residential and commercial finish work where a clean, consistent surface profile is required before priming, painting, or clear coating. The 300-grit extra fine grade removes fine scratches and scuff marks without aggressive material removal. It is commonly used on drywall, cabinetry, trim, fiberglass, and lightly oxidized metal surfaces. The hook and loop attachment system makes it compatible with standard random orbital and disc sanders equipped with a hook and loop pad.

Installation Notes

Attachment requires a compatible 5-inch hook and loop backup pad mounted to a random orbital or disc sander. Ensure the sander is powered off and unplugged before changing discs. Press the disc firmly onto the backup pad to ensure full hook and loop engagement before operating. Inspect the disc for wear or loading before each use and replace when cutting action degrades.
