These are very small. Worked great for drilling holes in a shells for wind chime.

I could drill into my beads before but the diamond surface really helps me to make them wider since the larger drill bit won’t fit in my hand jewelry drill. Works just like I needed!

I use them for making holes in the pearls. I’m still fairly new to this, but they worked fine while I used them on the electric drill machine. I might have not used it correctly and the very tiny ones broke on me but that’s because i forced it to much.

Good on wood but useless on metal

I purchased these drill bits to make holes in glass, and uv resin for my jewelry making. I will not recommend these to others. I am two days late for return, I am writing this review to help others decide if they are considering purchase. When drilling small holes into pieces as mentioned, the drill bit broke and flew off the bit.

As described. Seem to fit correctly.

perfect for the use i need to drill through stone and gems for jewelry making, recommend

Works very well.

I bought this for my granddaughter as she wanted to make jewellery from glass pieces collected from the beach

These are advertised as diamond drill bits when they are in fact not real diamond drill bits. I wanted this for drilling sea glass and it did not even dent it!

Very bad quality product. Could not even make a scratch on the glass.
