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

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

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

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

Got what I ordered. Super

So far so good! These are awesome for carving rocks and crystals. IMPORTANT, do not push hard, use water and let the bit do the work, otherwise (past experience, not with this brand) the diamond coating will wear out faster. I definitely recommend these!

Good but very small. Works on fine areas that need sanding on hard surfaces like ceramic.

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

Just the right set for tinkering, polishing and shaping

Quick delivery, items as described and good quality. They last quite a while, even on gun steel

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.
