ED sez: "Absolutely"

Yep! From the descriptions, a HF set for $29.95 looks as good as a Chicago-Latrobe set for $300.

I can understand your confusion here but it is also important to
include what type of material you will be drilling, as the best drill
bit for aluminum will not be the best drill bit for cast iron, etc.,
etc.

Hope this helps you.

Also, the basic steel is as important as the coating (if any).

The basic steel is much more important than the coating. Coatings are
cheap -- the thin, cheap coatings of TiN they put on cheap drill bits add
maybe 3 cents to the cost. They can be helpful on top of good steel. But put
them on top of Chinese "M50 equivalent" high speed steel, and you have
frozen crap with a thin, crusty coating. Crunchy on the outside, chewy on
the inside...

Then too, the process by which they are manufactured is as important as
the materials. Pretty hard to tell from the descriptions in the stores.
Best to rely on name brands and sources.
