I keep my small drills seperate from my bigger ones 1/8" on down in old pill bottles the same as my spot weld cutters.
They are easy labled that way for old eyes to read.I usually buy several at a time then when they get low buy some more.
Good quality bits last a long time if you take care of them and "DO NOT FORCE THEM" into your material. I also have a small battery operated drill motor that works well when I use the smaller bits.
I like the Cobalt Bits in the smaller sizes too.
