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

Got what I ordered. Super

I used a few of these tools so far. They seem to work great and seem very durable.

Handy for so many projects, packaging needs improvement so they dont come loose upon opening but they are handy as heck.

These bits removed pits of auto rust to bare metal in seconds. The variety of sizes helped in matching the bit to the pit! Will definately buy again but that may be a while as they seem to be long-lasting. Absolutely worth the price..

Works great for a few minutes but wears out quickly. You get what you pay for I guess.

The shafts bend easily with very little vibration. The heads do work as intended.

Ive been using these to clean up after I use the Dremel and so far so good. It leaves a smooth surface and different sizes has been great for those small areas that are hard to reach.

The grinding bits wear down to quickly, but they do grind.

It would be helpful if grit was mentioned in listing. Not bad for the price.

The diamonds rub off very easily. If you are using these outside of hobby DIY things , go with another brand
