For drill bits, just buy them online. MSC, Travers, J&L Industrial are good places to order with fast delivery.
And get a set of 0-1 mics. #61 thru #80 bits are only a thou or so different from each other. Chances of getting 20 from anywhere in all the correct sizes is a crapshoot. Get a 61 to 80 drill index to keep the smallest in

You will need a micrometer to keep up with the sizes as a "very near" caliper will only do that....get you near the size. haha
I got a set of 61 to 80 drills from Tower Hobbies. I think it was $14 or so works for me. I don't plan on drilling anything out with them...just check sizes of purchased Feed Restrictions.
Keep in mind that drilling a .020 dia hole is a pretty precision project for the home builder to do accurately.

I've always been told to use several drill bits , working your way up to the final size you need

|cranky1||Drago Supply or Grainger? And it's a good idea to have something to measure them to verify they are as marked. It doesn't happen often but I have found mismarked before....|

Small Drill Bits - Where to find them?
I'm working on tuning my Quadrajet (using the Ruggles book), and I need to be able to measure and resize various holes in the carburetor. I need a set of small drill bits in sizes about #52 through #80, and they are hard to find locally.
I found a pin vise set at Hobby Lobby that includes 12 bits, but they don't even list the drill sizes. I would have to buy a micrometer to figure out what I had.
I've also found the pin vise and drill bits online, but would like to find a local source so that I can just pick them up. Anyone have an idea of who might carry them? I'm in San Antonio, so we have most of the common chain stores.
