Custom sized for fine finish sanding of contours on hard-to-grind materials, the 3M™ Flexible Diamond 6457J is ideal for light pressure grinding. Metal bonding of the diamond abrasive to the backing ensures durability, while the open dot pattern reduces loading. Products with the smaller 18 generally will have finer finishes, whereas the B2 pattern will be more aggressive.
