grinding cutting buffing polishing drilling etc ect. Yesterday I soldered a ring that had broken then used the dremel to smooth out my solder job. I then changed tips and used it to polish the ring, Next project will be polishing two types of stainless finishes on my watch band. And sometime soon I will be cutting some drywall with it. I will also be carving some eggs in the near future. Heck it even cuts marbles in half
