Diamond Polishing Disc Set 6 PCS, ENLAYER 6Inch Diamond Flat Lap 80/400/600/800/1500/3000 Grit Wheel Lapping Grinding Disc Tool for Cutting or Sanding Stone and Glass (6)

Item as described, this my my own fault for not drying them properly after use but they will rust a little and wear out fast especially if your using them on a traditional flat lap, better suited for a facet machine.

Used for polishing rocks. Work fantastic. Great quality

It's only getting 4 stars because they didn't hold up as long as I'd have liked, but they were perfect for shaping my gemstones. I wish I could find them in some higher grits for finishing touches, but they worked great. Very well balanced and high enough quality discs.

Works great

So far so good. We'll see about durability and polishing speed later.

These are probably really good for sharpening tools or rough grinding but they are no where near the grit marked on the disks. The "3000" didn't polish at all. It scratched and abraded.

excellent job for my stones

Better than I expected at the price point. Worked well so far but I have not used them a lot. Sharpens and polishes the carbide lathe tooling well. If you are unsure then try them, I am glad I did.
