I have an index or 2 for jobbers bits and other sprial bits
Masonary bits live in a dormer bit box you get when you buy your bits by the 10s
Spades, brad points and butterflys live in a box or organiser
Sds live in a big organiser box
Brace and spoon bits live in a wooden tray with the brace
Forstners are in a wooden box (hilka sell their bits in one, the bits are ok but they've been replaced with better over the years)
Oddities live in a tray in the draw under the drill press (things like drill and counter sink combinations and reground spades)
Hole saws live in a wall bin at the moment but I need to find something better for them, Masonary hole saws have their own protective case
spares live in another draw under the drill press table, of which there is around 600 twist drills from 0.5mm up to 16mm and similar range in imperial, all on dormer boxes sorted by size.
I have a lot of drill bits, I inherited my fathers supply as well as my own.
for normal people without an addiction, buy or build a drill index.
