3M 7100188646 Wet or Dry Disc 5 Inch P600 Grit Ao

Product Description

The 3M 7100188646 is a wet or dry abrasive disc from the 3M Wetordry 281W series, built on a waterproof mesh cloth backing that resists loading during use. At 5 inches in diameter and P600 grit, it uses aluminum oxide mineral to deliver sharp cuts and fine finishes on a range of surfaces. The mesh construction allows the disc to shed swarf and debris, maintaining cut rate across wet and dry applications. It is primarily installed by finishing technicians, bodywork professionals, and metalworkers handling surface prep and final finishing tasks.

This disc is suited for finishing work on paint, e-coat primer, gel coat, and bare metal surfaces. The waterproof mesh cloth backing makes it effective in both wet sanding applications, where water acts as a lubricant and coolant, and dry sanding scenarios. The disc attaches to a compatible hand pad or backup pad using clamps or clips, making it appropriate for hand-applied finishing passes where controlled pressure and consistent scratch pattern are required.

Installation Notes

Attachment to a hand pad or backup pad requires compatible clamp or clip hardware; verify pad compatibility before use. When running wet, ensure the work surface and surrounding area are managed to prevent slipping hazards. Discs should be inspected before each use and discarded if the backing shows tears or delamination that could affect performance or safety.
