3M 7000120369 Hook and Loop Disc 5 Inch P400 Grit

Product Description

The 3M 7000120369 is a coated abrasive hook-and-loop disc designed for fine finishing work on a wide range of surfaces. Built on a lightweight A-weight paper backing with aluminum oxide mineral, this 5-inch disc delivers consistent cut at P400 grit while resisting loading thanks to an open-coat construction and a load-resistant surface treatment. Rated to 12,000 RPM, it is sized for use with standard 5-inch random orbital sanders. Finishing professionals, body shop technicians, woodworkers, and painters rely on this disc for final surface prep before topcoating.

This disc is suited for finishing applications on wood, primer, paint, sealers, topcoats, fiberglass, and plastics. The hook-and-loop attachment system allows fast disc changes and supports reuse across multiple passes, reducing downtime during production finishing runs. Typical use cases include scuff sanding between coats, featheredging paint, and smoothing filler on automotive and woodworking substrates. The open-coat layout helps maintain cut performance by reducing particle buildup on the disc face.

Compatibility

Designed for use with 5-inch hook-and-loop random orbital sanders in automotive refinishing, woodworking, and general surface finishing applications.

Installation Notes

Disc attachment and removal requires no tools — align the hook-and-loop face with the sander pad and press firmly to seat before use. Confirm the sander is powered off and unplugged before changing discs. Do not exceed the 12,000 RPM maximum rated speed. Inspect the disc for tears or delamination before each use and discard any damaged disc immediately.
