Almost as good as an
index, and you can have multiples of the common sizes that commonly
break or get dull. (80/20 rule applies to drill bits big time- 80% of
your holes will be made with 20% of the bits.)

I always hating using fresh drill bit sets. When you wear out/lose/break
one, finding a same-size replacement is always a pain. But like Sears
tools, sets are the only logical way to buy them- one-by-one is insanely
expensive.


Here is the plan for drill bits.

First buy an index that has 1 of each.

As these bits break, then you go to the machine shop supply and get
replacement bits for those sizes in quantities of 3-6.

You refill the index with a drill from the envelope, and then have all of
the envelopes.

On the more common sizes I also buy a pack of "stub" drills. These are
shorter than jobbers length, so they snap less, and most of the time you
really do not need the additional length.

I also use taps often, so I also get a pack of the tap drills for the common
sizes (8-32 10-24 10-32 1/4-20) and keep these drills with the taps. (You
may note I omitted the 6-32 from my list. This is because I refuse to use
that size because the screws and the taps are so course that they are way
too week.)
