I love these tools! I have 5 Dremels, Electronic, Battery, & single speed that I have a Dremel Speed Control hooked up to. My oldest is going on 40 years old. I 1st used a Dremel when I was in the Navy to repair electrical connectors. That's when I fell in love with it. I have cut off frozen bolts & nuts on cars & trains (the real ones). I have cut all model gauge track, modified all kinds of models, made my own moldings, cut BX electric cable rewiring my house, polished metals & plastics, cut tile, wood, formica, copper tubing, cutout for electrical boxes in drywall & cement board. Come to think of it there hasn't been much I haven't tried to use a Dremel on!
Your limited by your imagination. Go ahead & try one.
