3M 7100091094 Abrasive Disc 180 Grit 6 Inch

Product Description

The 3M 7100091094 is a 6-inch hook-and-loop abrasive sanding disc designed for paint preparation and body repair in automotive and refinishing applications. Built on the Hookit platform for fast disc changes, this 321U disc uses an aluminum oxide mineral base blended with ceramic grain to maintain consistent cut rate across the full sanding sequence. At 180 grit, it sits in the fine-prep range, suited for scuff sanding, blending, and finish leveling before primer or topcoat. An anti-loading coating keeps the cutting surface clear of dust and debris, extending disc life between changes.

This disc is used in automotive body shops and refinishing facilities for surface preparation on painted panels, body filler, and primer coats. The multi-hole pattern supports dust extraction through compatible backup pads and vacuum systems, reducing airborne particulate and keeping the work surface visible during sanding. The hole pattern is engineered to align with most standard backup pads used in professional body shop environments.

Key Features

• 180 grit aluminum oxide and ceramic blend for consistent cut and finish in paint prep work
• Anti-loading coating resists clogging from sanding dust and body filler residue
• Multi-hole pattern aligns with most backup pads and supports vacuum dust extraction
• Hook-and-loop attachment allows fast disc changes without adhesive
• Upgraded resin bond improves disc durability and surface finish consistency
• 6-inch diameter fits standard random orbital and dual-action sanders

Compatibility

Designed for use with standard 6-inch hook-and-loop backup pads on random orbital and dual-action sanders commonly used in automotive body and refinishing applications.

Installation Notes

Attach the disc to a compatible 6-inch hook-and-loop backup pad before powering on the sander. Ensure the backup pad surface is clean and free of debris so the hook-and-loop interface seats fully. Connect to a dust extraction system when using the multi-hole format to maintain visibility and reduce dust exposure. Follow applicable workplace safety and ventilation requirements when sanding painted or primed surfaces.
