I need to drill an 11/64 hole into HSS to tap and attach a carbide cutter onto a lathe tool that I fashioned. What kind of bit will do that? (nothing that I have seems to work.)
Slow speed, correct point on the MADE FOR HSS drill bit….LOTS of oil. And a can of "Tap-ease" for tapping the threads. Watch out for the bit "catching" on it's way through….CLAMP the part down..TIGHT.
Yeah either HSS or carbide will work. Like bandit said low speed and put some pressure on it and cutting oil makes a big difference. Are you using a drill press or a hand drill?

You just need good bits that are sharp. The tapping part can be tough but it's do able. Go slow a little back and forth with cutting oil or cutting paste and you'll get it done.
Well, if the HSS is hardened, you might get a carbide drill to put the hoke in, but you won't be able to tap hardened steel. What you can do it drill a clearance hole for the screw and put a nut on the bottom, if there is enough room inside a hollow form for the nut on the bottom
But if the HSS is NOT hardened, you can drill and tap it quite easily with a twist drill and you have to be very sure the tap is going straight into the hole.! I use low carbon steel when I make bars to hold carbide inserts.
Possibly, depends on the screwdriver Andy. I'd just take a file or drill to it and see if it seems like it will cooperate.
My recommendation would be 303 Stainless if you decide to purchase stock. It's plenty strong, it machines well and it's pretty corrosion resistant and non-magnetic. I prefer SST due to the humidity and rust around here. If that's not an issue for you, some low carbon steel will do just fine.
