The 3M 7100224417 diamond abrasive disc is designed for fine grinding and surface refinement on hard and abrasion‑resistant materials. With a 7 inch diameter and 1‑inch center‑hole mounting, this disc is intended for use with compatible grinders and backing pads where controlled material removal and smooth surface finishes are required.

Constructed with diamond abrasive bonded to a flexible cloth backing, this disc offers an extended service life and consistent cutting performance compared to conventional coated abrasives. The M250 grit micron pattern provides fine finishing capability, making it suitable for surface preparation prior to polishing, sealing, or coating on materials such as concrete, stone, ceramic, glass, metal, and composites.
