I can't seem to drill these guide holes even though I'm using a cobalt drill bit. What am I doing wrong?

I can't speak to what you are drilling but for metal in general you need to use oil to lube it and drill with a fairly slow RPM. I've drill a bunch hardened metal screwheads to attach safety wire(motorcycle) and that's what you need to do
