Electroplated diamond discs

SKU: 54-045


Hi-Tech Diamond electroplated diamond discs provide a flat grinding surface for both rough and fine grinding on stones and glass. Top-grade diamond powder is nickel electroplated uniformly onto a 1mm-thick steel disc, resulting in the highest quality disc available on the market. These diamond discs have a long lifespan because they are made of steel and are well-suited for more heavy-duty grinding. Diamond discs are used on our All-U-Need and Slant Cabber lap machines, and can be used on all other lap machines that accept 1/2″ arbors.

6″ and 8″ diameter discs are available in a large variety of different diamond grits. All diamond discs are available with or without a 3M pressure-sensitive, high-tack adhesive backing on the backside. Simply peel off the adhesive backing and apply to a backing plate for a permanent application.

Purchasing notes: Max RPM is 4,000. Discs require a backing plate. We recommend purchasing disc bushings with diamond discs that are not permanently bound to a backing plate, such as the discs without adhesive backings, to prevent all possible vibration and off-centered alignment that may occur.

Great, reliable discs...

I am very happy with the electroplated diamond discs. They are very consistent and seem to be holding very well. It does help to get an unimportant rock and run it over the discs with water very quickly when new. They are very well centered and mounted flush to the backing plate. I will purchase these again in the future.

Electroplated Discs from Hi Tech

8" diamond discs fit my acrylic backing discs perfectly and work as expected on my slant cabber. They save a ton of time when cold working glass. I have used these for several years.

Electroplated Discs from Hi Tech

I'm a newly emerging cabber who came across the Hi Tech brand while researching cabbing machines. It's a compact, affordable machine with a wide variety of different gritted discs. These electroplated diamond discs stand up very well to the grinding and shaping of my rocks. They are easy to clean and seem to be holding up well.

I have been using the 8" flat lap for several months now. I have tried 8" disks from other venders and they started showing rust and don't work as well. I can tell by looking at the the quality of Hi-Tech products are much better. I will be coming back for sure.
