I dont need to use one very often, but sometimes it’s handy. But I would probably use it more if it weren’t such a royal pain to get it out of the plastic case with its stiff unwieldy cord, and chuck up one of the tiny tools for ten seconds work.
So I see they make a cordless version now, and even one with a keyless chuck. Seems like a good idea. Do you use a Dremel? Do you have a cordless one?
