The 3M 00051115197383 diamond abrasive disc is designed for grinding and surface preparation on hard and abrasion resistant materials. With a 4 inch diameter and a 1 inch center‑hole mounting, this disc is intended for use with compatible grinders and backing pads where controlled yet aggressive material removal is required.

Manufactured with diamond abrasive bonded to a flexible cloth backing, this disc provides extended service life and consistent cutting performance compared to conventional coated abrasives. The M40 grit micron pattern delivers strong cutting action suitable for initial grinding, surface leveling, and preparation before finer finishing steps on materials such as concrete, stone, ceramic, glass, metal, and composites.
