Diamond Lapping Film Discs

Diamond lapping film discs are micron graded diamond particles resin bonded to a uniform 3-mil polyester film backing. This offers a cleaner, more consistent alternative to diamond compounds or slurries.  They are used to finish and polish hard-to-grind materials such as glass, ceramics, hardened metals, composites and micro-electronic materials for SEM and TEM analysis.  Used wet or dry.

PSA means "Pressure Sensitive Adhesive" backing is on the disc.  "Plain back" has no adhesive backing.
