Hi-Tech Diamond sponge pads are to be used under our diamond smoothing discs, Tech-11 polishing pads and final polishing pads to provide a cushion that helps remove flat spots from cabochons. Simply peel the PSA backed sponge pad and apply to a clean backing plate. Then, apply your smoothing disc or polishing pad directly on top of the sponge pad.
6"- and 8"-diameter pads are available. All sponge pads are 1/8" thick and come with a PSA backing for easy application on backing plates.
Much more flexible to get recessed areas, adds a little flex to adapt to the surface.
Useful thing. I made the mistake of not buying them right away.
Now I had to re-glue it and it didn’t turn out very neatly.
Sponge pads create very little flexibility. Just the way I wanted.
Why don’t you include these pads with the original cab machine. They are perfect for not leaving any flat spots. I used a 1/2 drill bit to center it on the disc.
Wow that is amazing the way you can get the edge dressed up much easier with these
A must have with smoothing discs. Good price.
