I have the 1/8 HP version of the Foredom that Rio Grande was selling back in 1987, it still is running its original flexable shaft and brushes, I have several handpieces for it. It is much more versatile than a dremel, and a whole lot more torque. The fact that the motor is not in your hand makes it much easier to hold and control than the dremel. I ditched my dremel and bought the flex shaft when I was cutting stone seat notches in a prong, and the bearings on the dremel wiggled in the plastic housing and the cutter moved, ruining the prongset. Dremels are cheap hobby tools and not really suited to precision work
just my opinion
