Oudtinx 50pcs Diamond Coated Grinding Head Grinding Burrs Set for Dremel Rotary Tool

These worked better than expected. They wear down pretty quickly but they’re cheap too. I don’t do a lot of grinding and used this to make a memorial stone for my dog. It did exactly what I needed and I’m very happy with the results.

These diamond grinding wheels work well on stone using a dremel. For longer grinding life, you need to avoid overheating them. This can be done by keeping the overall speed of the grinder in check, not trying to take off too much surface at a time, and with the addition of a water drip. For the overall price and functionality, they are a good price point.

I like the bit combination included in the set. I'm able to use the different bit combination to perform the different grinds needed. One thing to keep in mind is to consideration the material you are using these bits to grind and the Rotary speed settings (Check your Rotary Manual). That will determine the longevity and wear down of a bit tool. 🛒😁👍

Robust diamond grit, well adhered. I used diamond primarily on carbide and on harder tool steel, but my first test of these bits was cutting a hole in a ceramic pot, which was accomplished dry with no discernible loss of grit.

These work fine in my Dremel tool. I use them for the fine creases and veining in my wood sculptures.

Nicely packaged, but wear out very fast

Amazing price! These work wonderfully on pottery to make small or big adjustments. I like that there are so many pieces.

Used it on ceramic so far - it works just fine. Made my job way easier.

The burrs are exactly as advertised. I have used some of them to smooth the surfaces of some stones and they worked well. I feel they are good value.

Great product, wish the bits lasted longer. Depends on the hardness of the material but overall works well for what I needed it for.

You definitely get what you pay for and for the price you can replace as needed I guess. The Diamond grit wears off pretty fast. Faster on some bits than others. I would purchase again based on price not quality since I am new to my hobby. For information purposes I am using these on rocks to shape them for jewelry.

Love these
