3M™ Flexible Diamond Abrasives

3M™ Flexible Diamond Belts, Discs and Sheets are designed to help you achieve improved finishes on a wide range of hard-to-grind materials – without sacrificing cut rates. They ensure high precision and cut with long life and reproducible surface finishes.



A Nickel bond securely anchors micron-graded diamonds to a premium flexible backing in a dot or chevron pattern. This provides durability and long life, while allowing conformance to a variety of contours.

Resin Bonded grades will give reduced cut and finer surface finish than Nickel Bonded equivalent grades.
