Removing headless screw

I have a metal shower door with headless screw in the frame. The absence of the head means that the door doesn't close completely or properly at the bottom. I'd like to use a screw extractor to get the headless screw out and replace it with a new screw.

At the local Ace, the guy suggested an Irwin Cobalt drill bit. The package says "STARTS ON CONTACT". The bit does not start on contact, though. Granted, the screw is in an awkward position, but the bit is not biting into shank. I've started with slow RPMs and avoided bowing the bit, but it's not making a mark.

Is there some trick to getting this going, or do I need to try a different bit?

Do you have the drill in reverse?

First I'd use a Dremel tool to slot it and try turning it out with a flat tip screwdriver.

I hadn't considered that because the head is completely gone, and the shank is flush at the top. However, I may have to try my luck with that.

Sometimes the screws are made of hard metal .Do know what kind of metal they are?Use left handed drill bits.Start off with smallest drill and work your way up to the largest will work .If does not back out wth left handed bits you put a eze out in the screw and remove it
