I use rotary tools for polishing, or the final step in lapidary work and making cabochons. I review the various rotary tools.
Flex shafts are the best in my opinion for this kind of work but starting out, Harbor Freights rotary tool isn't bad, just remember to purchase a warranty with it.
Dremel has a life time warranty on all of their tools! So, never purchase an extended warranty for Dremels. if they fail, send them back to the service department, they will fix it or replace it.
