3M 7000120370 Hook and Loop Disc 5 Inch P600 Grit Ao

Product Description

The 3M 7000120370 is a hook-and-loop abrasive disc designed for fine finishing work on a random orbital sander. Built on a light A-weight paper backing with aluminum oxide mineral, this 5-inch disc operates at up to 12,000 RPM and carries a P600 grit rating. Open coat construction combined with a load-resistant coating keeps the disc from clogging during use, extending cut life and reducing the frequency of disc changes. It is suited for professional finishing passes on wood, primer, paint, sealers, topcoats, fiberglass, and plastics.

This disc is used in light finishing and surface prep applications where a smooth, consistent scratch pattern is required. The hook-and-loop (Hookit) attachment system allows for quick disc changes and permits reuse of the disc across multiple passes, making it practical for production finishing environments. Typical applications include automotive refinishing, furniture manufacturing, cabinetry, and composite or fiberglass panel work where fine grit finishing is the final step before coating or inspection.

Installation Notes

Align the disc squarely to the sander pad before pressing to engage the hook-and-loop fastening surface. Verify the sander is rated for the disc RPM before operation and confirm the disc is fully seated before powering on. Inspect the disc for wear, tears, or loading before each reuse and discard if the abrasive mineral is depleted or backing is compromised.
