I just carved my 1st lithopane and nailed it on the 1st pass. I'm using bits that my dentist gave me. Tons of different profiles. My dentist throws them out after every patient no matter how long he used it. He must have given me over 2000 in the last 2 years. Just ask your dentist to save them for you.
They are 1/16 dia.

I had previously asked my dentist about this. His answer was that they are carbide bits. If he runs them through the sterilizer, it erodes the edges of the bits and makes them too dull to use.
