For an exceptional finish on extremely hard materials such as ceramics, stone and glass, use 3M™ Diamond Lapping Film 661X. Our precisely graded diamond particles, applied to a polyester film, produce a uniform finish. Available in various grades ranging from 0.10 to 30.0 microns.

For the highest demands on surface quality on all extremely hard materials. All Diamond Lapping Films should be used ‘wet’. Water, emulsion or other commercially available coolants can be used as grinding aids.
