Generally speaking, its not a good idea. It can work if you have a large heavy drill press and take very light milling cuts but the smaller less expensive drill presses don't have much chance of working.

Drill presses are not designed to take side loading so attempting to mill with one often pops the chuck right off its spindle. Drill press chucks are usually held on by friction to a tapered spindle so side loading it just pushes it off. A mill has a draw bar that effectively bolts the chuck (or collet) to the spindle so it can't come off.

Also, a drill press normally has more run out than a good mill would have. That means even if you are able to mill with your particular drill press you won't be able to get as accurate a cut as you would with a mill....
