3M 7000120338 Abrasive Disc 80 Grit 8 Inch Hook Loop

Product Description

The 3M 7000120338 is an 8-inch coated abrasive disc designed for surface preparation work in auto body, metal fabrication, and woodworking applications. It uses a ceramic and aluminum oxide blend abrasive bonded with resin to a durable E-weight paper backing. The open coat construction reduces loading and clogging when working over fresh filler, paint, or bare metal. The Hookit hook-and-loop attachment system allows fast disc swaps without tools. At 80 grit, this disc handles shaping, leveling, and scratch refinement across a range of substrate types. Sold in box quantities with a minimum order of 5 units.

This disc is suited for paint removal, plastic filler and putty shaping, and scratch refinement on bare metal surfaces. The open coat construction keeps the disc cutting aggressively through fresh body filler without premature glazing. The 8-inch diameter fits random orbital and gear-driven sanders equipped with Hookit hook-and-loop backup pads. The 7- or 8-hole pattern on select versions supports dust extraction systems, reducing airborne particulate at the work surface.

Key Features

• 80 grit ceramic and aluminum oxide blend for aggressive cut rate and extended disc life
• E-weight paper backing provides rigidity and durability under load
• Open coat construction minimizes loading on fresh filler and paint
• Hookit hook-and-loop attachment enables fast, tool-free disc changes
• 7- or 8-hole pattern on select versions supports dust evacuation
• Resin bond secures abrasive grain for consistent performance across the disc surface

Compatibility

Designed for use with Hookit hook-and-loop backup pads and compatible random orbital or gear-driven sanders accepting 8-inch discs.

Installation Notes

Mounting and removal require no tools — press the disc firmly onto a clean, dry Hookit backup pad before use. Inspect the backup pad hook surface before each disc change; worn or contaminated hooks reduce holding force and can cause disc separation during operation. Wear appropriate respiratory protection and eye protection when sanding. Follow applicable workplace safety guidelines for dust generated by abrasive operations.
