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

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.

Useful. My wife builds doll houses and she really likes the set.

Works great on grinding glass

Love this product and have used it alot, forcing the bits will bend the ones that are long and pointy, but if you relax and let the bit do it’s job without adding your own force and pressure, they work nicely and stops the issue mentioned. The problem was the users fault and I would purchase this again certainly.

Has everything needed for working with stones, gems and all around materials, bought for jewlry making and has been very helpful tool.

Smooth off rough edges was never easier.

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

Works well on glass etching.

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