What thickness of stone will these drill?

I usually try to stay around anywhere from an 1/8th inch to 1/inch...I find that works for me..

Do you sell collet for dremel drill 1mm for these bits I just bought?

We have a 10 Pcs Brass Collet Set available on Amazon. This is the improved version of 2021. They fit Dremel rotary tools. https://www.amazon.com/dp/B0752WJSBL

Does anyone know the shank size on these drill bits? I'm looking for 3/16

The shank size is very close to 1mm, and would be approximately, 1/24 inch

Will these drill through animal bone (for jewelry making)?

I would think they would. I drill through fossils for jewelry making. I have to keep the stone wet, and periodically wet the tip of the drill bit.
