Nice!

USA made drill bit set, small sizes about up to 1/4" by 0.001 or 0.002
(I do not understand the principle), looks like all others, $5.

Are you sure that is not a number size (wire size) drill set?
60 drills ranging from something like 0.040" for the #60 up to 0.228"
for the #1.

Yes, it is very possibly that.

In which case -- *keep* it. Usually called "number size" or
"wire size" drills.

Those sizes are the best choices as the tap drills for many
smaller taps. I like having the fractional, number, letter, *and*
metric drill sets -- so between them you can usually find something just
the size you need -- including fine tuning the tap drill size when you
are tapping long threads in tough material. As long as there is enough
length to supply the strength when you have less percentage of thread
depth.

Enjoy,
DoN.
