It's an electric drill! It's some sort of Black and Decker model I believe, and it was given to the lab without working batteries. Being the enterprising souls we are, someone decided to modify a set of wires into the battery terminals, to give it juice from one of the bench supplies. This works somewhat well. If you don't know how to hook it up, ask someone.
Caution! It's a drill. Use common sense and don't put your hands where they don't belong while you're drilling.
Hook it up to the bench supply, flick it on, and you've got a drill!
Coil the cord up, put it away when you're done. Turn off the bench supply too.
