You need drill sets #1-60 and #61-80. 2 sets. The tiny bits need a really small drill chuck as well. You can find most of the stuff on eBay. Granted I know you have much more limited access over there so it may be a little more difficult. I think you’re going to learn a lot and I believe with the help here you should be able to get it tuned up.
The taps are just a basic machine screw thread. I am not sure of the abv on them.
