After ausgiebieger research (especially many reviews and tests) I decided to take a Dremel, Mannesmann etc. for the Proxxon and here for obviously something higher-quality alternative. The part about going great, is not too warm, and works as expected. In combination with the same time ordered Proxxon flexible shaft Micromot 110 B / F is a really perfect tool for my work with wood. Have for Christmas quite a bit tinkered. In a workshop, I have recently been working with Dremel and other brands, but the Proxxon seems clear sound and high quality. The speed of "only" 20,000 rpm ranges mE fine. But I admit that I almost always "full speed" driving during grinding and also for periods of 30 minutes or more at a stretch. The Proxxon seems however to mind. He is warm but not hot. I assume that the Proxxon will also be tough because he does not act intently at the work.
