About Finishing

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping compounds. Apply with cylinder laps, buffing wheels and bobs, or lapping sticks. Grit and microns are approximate.

Water-soluble pastes are for use where oil could contaminate your work surface.

Oil-soluble pastes won't cause corrosion.

Water-soluble/oil-soluble pastes are easier to clean up than oil soluble.

Diamond Lapping Slurries

Thinner than paste for easier, even spreading over flat surfaces, these slurries contain diamond, which is long lasting. Slurries are water soluble, so they are easy to clean and can be used where oil could contaminate your work surface. Use with a lapping machine or lapping plate. Apply to the plate and rub your workpiece on the surface to create a smooth, level finish. Grit and microns are approximate.
