3M 7100024044 Wet or Dry Disc 8 Inch P800 Grit

Product Description

The 3M 7100024044 is an aluminum oxide abrasive disc engineered for wet or dry finishing applications across a range of surface types. Built on a waterproof mesh cloth backing, this disc resists loading and maintains cutting performance through extended use. The open mesh construction allows water or lubricant to flow freely during wet sanding, while the aluminum oxide mineral delivers sharp, consistent cuts and fine finishes when used dry. At P800 grit, this disc is suited for fine finishing and surface prep work. It clips directly onto a compatible hand pad using standard clamps or clips for hand-applied sanding passes.

This disc is commonly used in automotive refinishing, industrial coating prep, and marine finishing environments. Typical substrates include paint, e-coat primer, gel coat, and bare metal surfaces. The P800 grit level positions it for final finishing stages where surface smoothness is critical before topcoat application. The clip-on attachment method makes it practical for hand sanding in contoured or detail areas where orbital tools are not suitable. Professional painters, body technicians, and marine finishing crews are the primary users of this product.
