I presume you mean a cordless drill. If so I've heard it mentioned but
haven't seen a successful one. There is/was a web site outlining the
use of a circular saw (120v) which appeared to work ok on DC. My
suggestion would be to use a old electric wheel chair motor and
gearbox. They are a bit heavy but are made for the job. I buy mine
