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

Used to remove dryed stucco on mixing tool. Worked like a charm

They are amazing. Work as promised although, wear out easily.

These diamond burr bits are great price and does an excellent job in sharpening the teeth on my King Power stump grinder. It does take some time, but it save the time and money on buying a new set while the old teeth can be sharpen a few times in their lifetime before replacements.

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.

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

These are great! I put off buying more diamond tipped burrs because I already had some and figured they were all the same but I was wrong and these are completely different! I believe they're even two different grits! The larger burrs are the Goldish diamond Grit while the smaller ones are the silver and more of a fine Grit! They've been great for woodcarving so far and I'm very happy with the purchase!

Work supper to remove wood, steel and other metals.

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.
