What about using Parabolic drill bits? Would that help?
No.
This is what happens when using a manual feed drill press, when the tool passes through the far side of the material it will grab the very thin web left and spiral in like an auger. This happens because you have no control over the feed rate, this is the same reason that it is often unwise to climb mill on a manual milling machine.
Try this, if your drill press has a spindle lock engage it slightly so that the handle has drag enough not to advance by itself when passing through the far side. This is what drilling into another piece of material as a base does, it controls the feed rate as if it hasn't passed through the material at all, this only works once however without moving the backing material for each hole. It also does not let the, for lack of a better term "burrs" that are created that spiral up the drill flutes to form, dulling a perfectly good drill is very silly.
Good luck
