Go to your local hardware store and buy the American made bits. If you are using a drill press, it will be a piece of cake. The last time I drill a bunch of 1/4" steel for a stair case was done with my local hardware store American make bits. I just keep spraying it with WD40. I had to drill something like 50-60 holes. I was only just able to kill 2 drill bits. Went to the grinder to sharpen it right up. Go slow and keep the bit cool. Once you see lots of smoke, back off and spray or put a little ATF on and around the little hole. Are you drilling tool steel? Try to get a bit that's been grind for steel. If you are using a drill press, it shouldn't matter all that much but... How many holes?
