Hi Ed: It's a mortice chisel and bit. It can be used in a drill press with a morticeing
attachment or dedicated mortice machine. The drill bit in the picture is withdrawn and does not show except for the end that is normally locked into the chuck. A an aside from this I once was in a Woodworkers Wharehouse Store, and someone was complaining that he bought a chisle an bit set and could'nt get it to work, it turned out that he tried to lock the chisel portion into his drill press chuck. He did 'nt have
a mortice attachment,so the chisel would cut a pecuiliar hole and then break. It was
very hard to keep a straight face at that point.
