Hi-Tech Diamond Electroplated
Diamond Lap Discs

Hi-Tech Diamond Electroplated Diamond Lap Discs provide a flat grinding surface for general lapidary and glass grinding applications. They perform both rough and fine grinding on stones and glass.

Both 6″ and 8″ diameter discs are available in a large variety of different diamond grits. All discs are available with or without a pressure-sensitive adhesive backing.

Top-grade diamond powder is nickel-electroplated uniformly onto a 1mm-thick steel disc. These diamond discs have a long lifespan and are well-suited for more heavy-duty grinding.

These diamond discs are used on Hi-Tech Diamond's All-U-Need and Slant Cabber lap machines. They can also be used on all other lap machines that accept 1/2″ arbors.

All diamond discs are available with or without a 3M pressure-sensitive, high-tack adhesive backing. Simply peel off the adhesive backing and apply to a backing plate for a permanent application.


Max RPM is 4,000.

Discs require a backing plate.

If you order a disc without adhesive backing and do not plan on permanently binding the disc to a backing plate, we recommend purchasing a disc bushing to prevent vibration from off-centered alignment.
