Is there a make of drill bits that actually work? I'm doing a load of stainless steel things and whatever i use seems to take forever.
HSS is perfectly good for stainless steel. Above all you need:Makita cobalts at the moment with lube but they seem rubbish.
I bought some Dormer drill bits a few years ago for some steel and stainless steel work a few years ago. Worked very well and stayed sharp.
An acquaintance and steel fabricator advised me years ago that there was a lot of rubbish talked about 'special' drill bits and that all you needed for stainless was 'a half-way decent hss bit that is SHARP' ever since I've tended to start a job by sharpening several drill bits and using each for no more than one or two holes before replacing; re-sharpening the lot if/when I run out.
The other 'trick' I've discovered, though by luck rather than good management, is to use an 18.8 volt cordless drill on its slow-speed setting', but rather than fitting the battery, connect it to a 12-volt one, this gives a lovely speed for drilling stainless.

I wish I could do that! I consider myself a failure as an engineer because I can't (repeatably) get them right. Every now and then I get one right and it works very well, but most of the tim, the results are "variable"! I just have a real blind spot when it comes to drill sharpening!Teach yourself to sharpen your bits on the bench grinder and you'll never need 'special' bits again. I make mine very coarse and they rip through stainless like butter.
The trouble is, a lot of the things yotties want to drill is pre-abused, work hardened ss.I wish I could do that!

On the OP's point, my thoughts are:
(a) ......(d) As has also been said, slow is good. Once the drill starts to "polish" the workpiece, you've had it - literally a couple of seconds and the drill bit is toast.
