Stone Carving Set Diamond Burr Bits Compatible with Dremel, 46Grit 150Grit 24PCS Polishing Kits Rotary Tools Accessories with 1/8'' Shank for Engraving, Grinding, Stone, Rocks, Jewelry, Ceramics

I really like these! 2 grit sizes, one was very coarse and removed my stone carving quickly, and then the lesser for finer detail. Good value and they are holding up very nice. I carve rocks with a high speed dremel like tool and I go through these and the coarse one like 60 frit saves me some time.

Very nice. Good price. Lots of bits. Good quality. Used only once so far but worked fine.

Work great on my terrier's black claws. Much faster that the sandpaper and does not seem to get hot like the sandpaper. He didn't seem to mind them at all. I heard an a pet groomer recommend diamond Dremel bits on his YT channel, so I am glad I got them.

They do a good job at a good price point. Shanks are pretty weak. I tried to get a little more length out of a bit so I could get more reach with a while keeping the not flat by not pushing it in as far. I had a tiny wobble in my Dremel and the shank gave out. Pretty good bits overall, but don't try to get any extra length out of them. Would give 3.9 if Amazon allowed decimals. Can't complain too much for the value

So far, they seem to work well. (I'm using these to sharpen a serrated blade, and it seems to work OK.) However, they were all dumped into two bags; the different coarseness determined which bag. This also meant that the diamond was scratching to heck the 1/8" shaft. The significance of this is that after use, it was very hard to remove the bits from the Dremel tool since the shaft is now rough. Personally, I would have paid the extra 10¢ to have them individually placed in a strip of plastic. If they had done that, I would have given this a 5star review.
