>>6092773I use this AA battery powered one (Dremel 7000-N/5) that doesn't generate much torque. I'm not sure if they still manufacture this model.
I also don't use a sanding drum, but a split-pin mandrel...you need to insert strips of sandpaper to turn them into flap-sanders. This flapping also generates minimal torque.
See, if the torque is high, there will be enough friction to melt and splatter the plastic. Not good for your face.
