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.
30 and 35 degrees are typical angle for chainsaw teeth, like the other
writer mentioned. Conical just means it's been used a lot, and the grinder
tip is worn out. Or, someone ignorantly put a different tip into the device.
