3M Diamond Microfinishing Film Discs

Designed for fast finishing on stone inlay, glass, ceramics, non-ferrous metal, etc. These Hookit™ (loop backed) backed discs have micron graded diamond mineral electro-statically coated and resin bonded to a 5 mil polyester film backing. These discs are the best choice to provide the finer finish needed after leveling using the 500D above as they will leave a very consistent scratch pattern. They will far out perform aluminum oxide discs for this task as those can leave inconsistent scratches and wear out quickly. Can be used wet or dry; wash to clean.

Available in 2" or 3" sizes in 120, 220, and 320 Grit
