Hi,
could somebody point me to drill bits made for drilling gems, semi precious stones, may be crystals, in the 0.8-1mm range. I know a lot of Chinese bits and pieces on ebay. But not that. No Dremel tools.

This is for a friend, I need Pro quality tools that could be used longer, we are not talking drilling 2 stones here. A mini mill for that or +High Speed Spindle?

Any help will be appreciated! Thanks
