Levi, I have never been successful engraving into graphite. You might be able to get a very light surface mark on a graphite block, but they really eat up the power.

IF you are talking about engraving on graphite composit, forget about it. The difference in density between the graphite and the "epoxy" make it burn bubble and char.
