You can do it the other way, Dremel in Proxxon Press with an adaptor.
Why the Micromot?. They are both the same. Micromot runs to 20,000 rpm while Dremmel to 35,000 rpm
Dremel is a lot cheaper to buy and Fix. I have 2 of them, the second one I got on special for $49 as a complete Hobby kit.
Whilst Proxxon gear is nice ( have a lot of it), in relation to the rotary tools its hard to justify to cost.
