3M Trizact Diamond Tile, 677XA Type PC Sheets
Compared to slurries, this structured diamond abrasive removes stock faster, reduces sub-surface damage, and produces a finer intermediate finish that reduces polishing time on a variety of optical lenses and components. Polycarbonate backing adds the rigidity required for discs and sheets larger than 9 inches. Available in 3, 6, and 9 micron grades.
