Just get a decent lip-and-spur drill bit (one with a pointy bit on), put your victim on a level surface and drill nice and true into correctly marked out points - even with a drill press you're only as good as your marking-out.
Oh shit it's metal so ignore that bollocks. Mark out with something scratchy, centre punch it and use a nice sharp drill bit. The machine screw threads will be coarse enough to give you a bit of play anyway.
