3M 7100192040 Abrasive Disc 5 Inch P800 Grit Wet or Dry

Product Description

The 3M 7100192040 is a 5-inch wet-or-dry abrasive disc designed for fine finishing work on a range of substrates including paint, e-coat primer, gel coat, and bare metal. Built on a waterproof mesh cloth backing, the disc can be run wet to reduce heat and extend abrasive life, or run dry for convenience on the job. The aluminum oxide mineral delivers sharp, consistent cuts with fine finish results. The mesh construction helps prevent loading, keeping the disc cutting efficiently through the work surface.

This disc is suited for body shop and metal finishing applications where a controlled, fine grit cut is needed at the P800 level. It attaches to a standard hand pad or backup pad using clamps or clips, making it practical for hand-guided finishing passes on panels, primed surfaces, and gel coat repairs. It is used by auto body technicians, painters, and finishing tradespeople in both production and repair environments.

Installation Notes

Attach the disc to a compatible hand pad or backup pad using the clamp or clip mechanism before use. When running wet, ensure adequate water flow to the work surface to manage swarf and reduce heat buildup. Inspect the disc before each use and replace if the abrasive layer shows wear, loading, or separation from the backing.
