Cordless Drill (no batteries required) (Havant PO9)

I am looking for a drill whose batteries are dud, that you would be thinking of taking to the recycling tip.

This is to use on a boat, where we can wire it to the boat's battery supply. This is quite easy to do, but the old tool is worn out. We don't need the original drill batteries.

12v or 18v or thereabouts will be fine.

Thanks in advance!
