Actually, if you see those marks on the drum, that is where the tool used to remove the drum head top. See the middle picture where he shows how the grate support bolts are installed and you can see he removed the top. The bung hole tip would be handy though, if you are building a flat top UDS, and you would still be cutting off the top.
