Unfortunately, the photo does not show enough detail to determine exactly what you are referring to when you say drilling equipment. So, a guess. If you are referring to the setting of the gems in the metal bead, then you probably would need: A precision caliper, to measure the stones, appropriate size 90 degree hart burrs, appropriate size twist drills, a rotary tool, flex-shaft or Dremel, and a setting tool of some kind. The kind of setting is unclear in the photo. Since the bead exhibits certain brilliance, the setting could have been done using a graver and a beading tool. The graver would be used to push tiny curls of metal against the stone and finished with a beading tool. In addition to all of the above, you will need some kind of magnification and some kind of engraving block to not only hold the bead, but rotate it round and round. All of this is not easy to master.

It is not easy to master, I agree and there is no way I would even attempt to drill something that thick. It takes me over a hour to drill through 6mm of rock, that is not a hour of setting something up and walking away but of constant attention. Reach out touch your keyboard and as soon as you feel pressure lift you finger and do it again, that is what it takes to hand drill without ruining the bit or the stone or both at the same time. Few Lapidarys offer drilling, I used to get drilling questions two or three times a day everyday. If you are really determined to do it send me a message and I will walk you though it including where to get what you need. This would turn into a book is why I am not doing it here.
