3M Diamond Discs

Designed for fast Leveling on stone inlay, glass, ceramics, non-ferrous metal, etc. These Hookit™ (loop backed) discs have micron graded diamond, metal-bonded into the nickel “islands” on the disc surface. The islands are resin-bonded to a strong flexible backing in an open dot pattern. They have a very aggressive cut, but produce a consistent scratch pattern. They will cut better and last longer if used with water or at least dampen them during use. Non-loading, simply wash or blow them out to clean. These are 250 Micron (the approximate equivalent of 70 grit). Use the Diamond Microfinishing Film discs sold below after leveling to further refine the surface.
