Rotary Tool Diamond Burr Set for Grinding, Carving, Notching, Bur Bit - 🛠️ Ideal for Stone, Tile, Glass, Lapidary, Jewelry, Die Grinder - Coated File Cutter Cutting Kit Review

These tools were used to cut a steel segment from a TV bracket. It was slow but the job was done. Very good, hardened/reliable drills.

used for simple wood carving. A variety of beats is useful for different effects. I've used them not long ago so not sure about durability but so far so good.

I've just started using these bits and so far they're working great. It seems really durable and should last a long time. And the price can't be beat for what it comes with.

The picture was blurry and it was difficult to tell if the wood engravings were real. This honeymoon ended in a hurry. I keep them as a reminder to keep my eyes peeled and even when I'm frustrated I don't buy something like this for what I'm doing. And one day I will be able to engrave on glass. I gave them an excellent durability rating as I expect never to use them.

I'm literally amazed at the accuracy of these bits. The only downside was trying to find a collet that would fit my Dremel - I ended up grinding one down to fit. I live in Gold Beach, Oregon and there are so many beautiful rocks thrown in the sand it's amazing. I'm an artist and I decided to carve small stones. these bits also facilitate detailed work (not shown in the sequence). They are sharp and the accuracy is incredible.
