Sorry but I dont have a picture. Anyway it looks like a little Dremel grinder with a conical grinding tool in the chuck. It also has a guide around the chuck with 30 and 35 degree markings on it. The guide looks somewhat like an airplane with the grinder in-line with the wings. Power connection is heavy duty gator clips, Im guessing it may run from 12 vdc and they seem to be factory installed. It came in a box of misc tools I bought at an auction.
