Are there similar machinery available on the US market?

This is my old well used electric midget drill. The mm/inch caliper is only to show the seize of the drill.
This is here in Germany a fairly common Proxxon 12V drill. I have choosen the simple variant without electronic speed variator.
A ordinary Model RR DC transformer will give juice at variable Volts. It is important when drilling in plastic to to this with rather low rpm's.
The also availabe special transformers from proxxon for the drills machines will cause them turning at minimum 5000+rpm till 30000rpm.
With this rpm's you can simply melt plastics
So my homemade solution with the RR transformer avoid such melting.
The chuck will take drills from 0.3mm to 3.2mm.
The have even a US dependance: <!-- m --><a class="postlink" href="http://www.proxxon.com/us/">http://www.proxxon.com/us/</a><!-- m -->
