Heller drills are ok. But in my experience, most if not all mini drills sold on ebay as single sizes (not in a set of 100 assorted drills) are ok. For carbide, I get the cheap ones from alliexpress, they are fine

But these days I'm mostly using the carbide bits,

I may be wrong about this, but as I understand it:

carbide is mainly suited for use with metals like steel.  They stay sharp longer but they are also brittle and allow for little lateral deformation. 

HSS allows for flexing.   but quality steel is probably worth the extra.

Anything McMaster sells should suffice for your needs. You probably won’t know the manufacturer until you get them as they can source from multiple vendors. You are looking for high speed steel in either bright finish or black oxide. The more exotic coatings are for serious production scenarios.

 

if you care about manufacturers you can call McMaster and they will tell you or you can order from MSC or Travers which list them in their catalogs. You would be looking for ones like Guhring (my usual go-to), Chicago-Latrobe, Precision Twist Drill, Hertel, Dormer, or Cleveland. In smaller sizes the point and flute types don’t matter so much.

 

If you can find them in the size you need, consider screw machine drills. They are shorter than standard length jobber drills. This makes them a little easier to manage in less than perfect setups.

McMaster Carr is easy to navigate, has good quality and has  a LOT of choices.    The least expensive ones at MC are MUCH better than the stuff at Micromark.   As said above and many time before, quality is not cheap and as you can see from the responses, there are other sources of quality bits as well.  No matter the quality, for the tiniest sizes, consider buying several of each as it is no fun when one breaks and there is no back up in the bin.
