I have had really bad luck with dremel tools
as the variable speed control always dies within a few weeks of my
having it. Maybe they just aren't made for metal working.

....odd, I have been using my dremel for metal work for 20 years and never
had problems with the speed control. I have broken the little plastic
connecter between the moter and the bit section twice now. At one time
Dremel and Craftsman were the same thing. Is that different now?
