About Finishing

About Sanding Abrasives

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.

Lubricants for Diamond Lapping Paste

4 fl. oz. Bottle

32 fl. oz. Bottle

1 gal. Bottle

Use during lapping to prevent your paste from drying. Choose a lubricant that has the same solubility as your paste.

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

Oil-soluble lubricants won't cause corrosion.

Water-soluble/oil-soluble lubricants 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.

Diamond Lapping Grains

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains. Mix with oil, grease, or water to create your own lapping compounds. Grit and microns are approximate.

Natural diamonds are sharper and cut faster than synthetic diamonds.

Lapping Plates

Smooth

Grooved

Use these precision-ground plates with lapping compounds to create extremely flat surfaces on your workpiece.

Smooth surface is for very fine lapping with small abrasive grains.

Grooved surface captures the abrasive and holds it in place during lapping.
