This Dremel rotary tool clone is a great deal at $21

Dremel rotary tools are useful but pricey. I bought this $21 clone in 2017 because the Dremel tool I owned was cordless, and not really strong enough to rough out the wooden spoons I was whittling. It accepts Dremel bits (If you don't have any Dremel bits, no problem -- it comes with a good starter assortment). It has plenty of power. I have never turned it up more than halfway. I really like the flexible shaft, because it gives me more control than I have holding the relatively heavy tool itself.
