Electroplated diamond discs
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.
For me, the fact that the plates last as long as they do make me more productive than otherwise. There's been more than one occasion where I have called and found their customer service excellent.
