Important purchasing note: These smoothing discs are sold individually.
Hi-Tech Diamond diamond smoothing discs ensure rapid removal of scratches and high spots on cabochons. They also smooth large, flat areas in channel inlay work and are perfect for smoothing, refining and polishing a wide range of material such as glass, gemstones, synthetic material and even metal. These diamond smoothing discs come with our All-U-Need rock/mineral and Slant Cabber rock/mineral lap machines.
Using a proprietary technique, Hi-Tech Diamond diamond smoothing discs use a high concentration of premium diamond that is loaded onto each disc to provide an extremely aggressive grinding rate yet leaves an exceptionally smooth surface finish. Each disc is color-coded to easily determine what grit the disc is. These diamond smoothing discs are guaranteed to out-perform silicon carbide sanding discs and other diamond compound finishing systems. They do not crack or peel.
6"- and 8"-diameter diamond smoothing discs are available. All discs come with a 1/2" arbor hole and 3M pressure-sensitive adhesive backing that bonds to backing plates, flexible discs and polishing heads. Optional sponge pads may be inserted under these smoothing discs to create a soft touch for cabochon work.
Please note: You will need a backing plate to use these smoothing discs.
Customer Reviews
First: this review focuses on pieces that are dome polished! This is VERY important, because it's literally impossible to do a perfect flat polish on harder materials like jasper&agate. This is a big problem because these pads are marketed otherwise and I am very disappointed by this fact. Trust me, I tried for months but the pads are not aggressive enough to deal with a larger surface area on hard materials.
The pads up to grid 600 work GREAT, no problems there. Fast, easy, effective, five stars for those.
BUT: even when you're working on a domed jasper or agate it can take ages to get every scratch out from the previous 600 grid stage with grid 1200+
I don't really know why that is, maybe the jump from 600 to 1200 is just too big with these pads and there should be a 800/900 grid option? The 3000 grid pad has the same problem + it will create scratches that can only be worked out by going back one or two grids. I use the grids up to 1200 and then I go straight to polish with cerium oxide powder. Using this method I'm able to get an absolutely perfect finish very often but not always. I think hightech diamond is using diamond powder for the pads in general that is not perfectly sifted to one size.(Essentially not the highest quality, probably because of the lower costs) This doesn't really show up on the rougher grids but it's a problem after the 600 grid. I wish you would change that because this could be one of the best polishing products/machines ever.
Overall not a bad product but there is definitely room for improvement! Thx for reading :)
I bought a few that were in between that didn't come with my kit, and I also bought some that did, and with foam pads underneath them. So I have 2 complete sets, one with hard to the disk. And one's with the foam pad underneath for more rounded, rocks working perfectly couldn't be happier.
Purchased a disc that did not come with the kit, excellent product
Great product. Wish they lasted a bit longer but well worth the purchase.
My only complaint is they wear out quickly.
That shine tho!!!
