I want to drill a small, clean hole (about 2-3mm) through a coin to use it as a pendant. What type of bit or tool should I use?

use a high speed drill motor, and a quality drill. when I was young (long time ago) I made rings out of silver quarters and half dollars. you had to drill out the center, then slowly hammer it into shape, then lots of fine sanding and polish. believe it or not, I made some nice rings. also during the civil war some soldiers would put a hole in a coin, sand down one side and engrave there name into to it for identification.

a drill with a bit in it ( the bit is essential )
coins are very soft metal you don't need a cobalt bit or something fancy any high-speed bit will work ( the spiral type not a spade type wood bit )
to warp a coin by drilling you would have to try really really hard - once again soft metal very little heat generated - it would be helpful to use a pin punch to start the hole so the drill doesn't slip and mar the coin ( a nail or anything with a point will work - this is a minor project )

You can use a high speed drilling machines used for the PCB boards drilling purpose with the help of HSS drill bit available in cutting tools stores.

I have clamped the coin to my bench and used a 1/8in drill bit before and it was clean, if you got a drill press that would work to but I think its over kill.

If your making a pendant then use a hole punch. The punch will not warp or spall the coin like a drill bit would.

First, you do know that altering US Money is a felony, right? Destruction of government property and all that.
Screw gun, metal drill bit, very small. After which, you can use a bigger bit to enlarge it. Go Slow.

Use a 3/32 inch high speed drill bit. 2.5mm =.098 inch 3/32 inch= .094 inch.

use an electric drill with whatever sized bit you want.
