3 micron Diamond Lapping Film + Backer
A set of 5 deluxe diamond lapping films + 1 aluminum backer. This film is 3 microns or 6,000 grit. This should be the third grade used after your 3,000 or 6 micron lapping film. Be sure and use a trailing stroke to prevent cutting the film. Use a hair dryer to loosen old film adhesive to replace the film.
