3M 7100091243 Abrasive Disc 6 Inch 40 Grit Hook Loop

Product Description

The 3M 7100091243 is a 6-inch hook-and-loop abrasive sanding disc designed for paint preparation and body repair work. The disc uses an aluminum oxide mineral abrasive blended with ceramic grain to deliver consistent cut across a range of automotive and industrial sanding applications. A multi-hole pattern promotes dust extraction and aligns with most standard backup pads. An anti-loading coating helps keep the cutting surface clear, extending disc life between changes. This disc is typically installed and used by auto body technicians and surface prep professionals working through paint system stages.

This disc is suited for automotive body repair, paint prep, and surface conditioning work where consistent material removal and finish quality are required. The 40-grit rating positions it for aggressive stock removal and initial surface preparation stages. The multi-hole configuration supports use with dust extraction systems, reducing airborne particulate at the work surface. The hook-and-loop attachment system allows fast disc swaps without tools, keeping workflow moving during high-volume repair operations.
