The “D’LITE” Diamond-Resin-Bonded faceting laps are currently being offered in seven(7) grit sizes from 325 to 50k. Just use water as lubrication!
Must be used with a master backing lap. The resin surface allows a finer finish with diamond of the same grit than you will get on a diamond electroplated lap. For example, a 325 D’Lite will behave like a 600 diamond electroplated lap.
