3M 7100091099 Abrasive Disc 500 Grit 6 Inch Hook and Loop

Product Description

The 3M 7100091099 is a 6-inch hook-and-loop abrasive disc designed for paint prep and body repair sanding applications. Built on a 321U backing, the disc combines aluminum oxide mineral with a ceramic grain blend to deliver consistent cut and finish across a range of automotive and general surface prep tasks. An anti-loading coating helps resist clogging at the cutting surface, extending disc life during use. The multi-hole pattern promotes dust extraction and aligns with most standard backup pads. This disc is installed and serviced by automotive body technicians and general refinishing professionals.

This disc is suited for fine finish sanding at 500 grit, making it appropriate for final paint prep stages, scuff sanding, and between-coat work on automotive body panels and painted surfaces. The Hookita hook-and-loop attachment system allows for rapid disc changes without tools, reducing downtime during production work. The multi-hole format supports connection to vacuum-assisted sanders and dust extraction systems commonly used in body shop environments.
