It looks like you hit the mother load. The tool in the first photo is expensive and almost impossible to find.  I

Not impossible if one can part with CHF 3,900 - 4,350 at the link posted above.
By coincidence someone posted about the Horia website which I promptly visited, and was able to recognize here. Wonderful tools.

The tool in the third photo is a small general use drill press. It is good for drilling applications that do not require a high rate of speed. Extremely tiny drill bits will break if turned too slow. I have a Dumore high speed drill press that turns at around 20,000 rpm and is suitable only for extremely small diameter drill bits.

Yes. Attached a recommended speed chart from Ruko. They have a lot of drilling and cutting information on their website.
