JINGLING Diamond Grinding Bits 3mm Spherical Head Burrs w Shank 2.35mm Pack of 30Pcs

I bought them to engrave a bottle and they worked amazingly. I was a first timer so was scared.

I’m impressed. I ordered two sets, the grit and shape is pretty uniform across the board, I had one that arrived broken though. Was surprised to find each came with a collet to fit a dremel. The fact I can get 60 of these for just over the price of one name brand is mind blowing. In use, they are lasting as long (if not longer) than dremel brand, with a more uniform wearing of the diamond grit. This is going to save me so much money.

Great for drilling holes in glass

Cheap, gets the job done.

Great for engraving on glass.

Good quality diamond ball burrs. I like that this seller sells sets with one size and shape. I used to have to buy assortments to get a single 2mm ball burr that i mostly use.

They sent me 2mm bits instead of 3mm. I am still using them, but need to enlarge the hole with my one remaining 3mm bit. (Drilling holes through polished stones) Not the best bits in the world, but for the price I can't complain too much. I would reorder them, but really don't want more 2mm bits. LOL I would give 4 stars if they were the right size.

Love these. They are perfect and they fit in my engraver machine. They are smooth and I love that they come with an extra piece if you need to fit them to something else! I have bought these in a multitude of sizes.
