I have quite frequently to drill stainless steel parts. And can say what trying, for example, to make ventilated screw from SUS304 standard screw is very low-yield task. Slightest error in feed rate of manually operated drill press, and SUS304 steel hardens, overheats, and destroy drill bit, all in a fraction of second. On the other hand, drilling a standard (iron-carbon-manganese) steel is not a problem at all. But standard steel is not corrosion resistant enough, especially inside the hole where no plating remains.

What i would like is some alloy with good corrosion resistance, but with decent workability. Internet search yielded SUS430 (4016 steel), but i am not sure if it is workable enough for my particular case (manually lowered drill press). Do anybody have some hints on how to drill stainless steel? Or on SUS430 drilling in particular?
