3M 7100199638 Abrasive Disc 6 Inch 180 Grit Ceramic Ao

Product Description

The 3M 7100199638 is a 6-inch hook-and-loop abrasive disc designed for automotive paint preparation and body repair work. The disc uses a blended mineral construction that combines ceramic grain with aluminum oxide abrasive, delivering consistent cut and finish across a range of sanding stages. A multi-hole pattern is built into the disc to support dust extraction and reduce material loading on the cutting surface. Anti-loading coating keeps the abrasive face clear during extended use. This disc is primarily installed by automotive body technicians and collision repair professionals.

This abrasive disc is suited for flat and contoured panel sanding during automotive refinishing operations. Typical applications include featheredging, primer surfacer sanding, scratch refinement, and final paint prep work. The multi-hole layout aligns with most standard backup pads used in production body shop environments, making it practical for high-volume repair workflows. The Hookita hook-and-loop attachment system allows for rapid disc changes without tools, reducing downtime between grit stages.

Key Features

• Ceramic and aluminum oxide mineral blend for balanced cut and finish performance
• Multi-hole pattern aligns with most backup pads and supports dust extraction
• Anti-loading coating reduces clogging and extends disc service life
• Hookita hook-and-loop backing enables fast, tool-free disc changes
• Upgraded resin bond improves disc durability across extended use cycles

Compatibility

Designed for use with standard hook-and-loop backup pads that accept 6-inch multi-hole abrasive discs in automotive body repair and paint preparation applications.

Installation Notes

Installation is performed by automotive body technicians using a random orbital or dual-action sander equipped with a compatible hook-and-loop backup pad. Ensure the backup pad is free of debris and that the disc seats fully before operating the tool. Operate at the sander speed recommended for the substrate being worked to avoid burn-through or disc glazing. Inspect the disc regularly during use and replace when cut rate drops or loading is visible on the abrasive face.
