Even in a drill press, I don't like 'em. They can catch on the work
piece and fling it who knows where. Use them if you must, but a hole
saw is much more user friendly.
I've used this kind on metal and wood in a drill press with the work
clamped.
I really think this kind of cutter was made to cut wood judging on how
it worked.
In any case I wouldn't use it on steel, only soft metals such as copper
or aluminum, and
then with a wood backing board.
