3M 7000120347 Hookit 255U Abrasive Disc 100 Grit 8 Inch

Product Description

The 3M 7000120347 is a coated abrasive disc from the Green Corps Hookit 255U line, designed for aggressive material removal and surface refinement in automotive and metal fabrication applications. Built on a durable E-weight paper backing with a ceramic and aluminum oxide blend abrasive, this disc delivers consistent cut rate and extended service life. The open coat construction resists loading, making it well suited for work on fresh body filler and painted surfaces. Hook-and-loop attachment allows fast disc changes without tools. This disc is used by body technicians, metal fabricators, and surface prep professionals.

This disc is intended for use on automotive body panels, bare metal, plastic filler, and painted surfaces requiring paint removal or scratch refinement. The 8-inch diameter fits standard random orbital and disc sanders equipped with a compatible Hookit hook-and-loop backup pad. At 100 grit, it is positioned for intermediate stock removal and surface leveling after coarser shaping work. It is sold in box quantities with a minimum order of 5 units.

Installation Notes

Installation of abrasive discs should be performed with the sander powered off and disconnected from any air or electrical supply. Align the disc squarely on the backup pad before applying pressure to seat the hook-and-loop interface. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the backup pad. Follow applicable shop safety practices including respiratory protection when sanding painted surfaces or body filler.
