Electroplated diamond discs

SKU: 57-045


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.

Impeccably Good

When I saw the price of these, I felt as though they would be ok, at best. However, they exceeded my expectations, greatly. Sometimes, you do not get what you pay for, but in a good way. This is one of those times. I will keep buying through this company for all of my cabochon making needs.

Like butter

I enjoyed how they chewed up the stone like a chainsaw rocks sawdust.
