Anyone know what size a 14 gauge needle is in drill bit form?

Title!

I'm trying to imitate a micro coil build I saw on youtube. He uses a 14 gauge blunt needle to build his coil. The needles comes in packs so I was wondering if I can find a drill bit of similar size.

0.064" or 1.628mm. There is no drill bit you're going to find that matches that, so just order a few needles.

Well, doing a quick Google I found that:

edit: never mind, read the chart wrong

Don't know if this helps, but, I've been using a dressmakers pin for wrapping my coils. It's roughly the same size as a 14 gauge needle and solved all the hassle of finding a 2.5mm drill bit.

Well, doing a quick Google I found that:

14 gauge = 0.182" = 4.623 mm

That equates to a 3/32 bit

This chart was for wire sizes....

I wrap all my coils on a 14g piercing needle. It comes in handy, especially when you need to get into places that other objects can't fit in.

You've got some good info on needle gauge sizes and wire drill bits. Here's a online coil building calculator that may help you modify one wrap diameter to another. I've used it so I know it's pretty accurate.

Well I found this chart from a ear piercing site. Not sure if this may help me identify which drill bit to use or not. Based on this chart, I should be going for a 1/16 drill bit

I believe a 14 gauge needle is 0.083" diameter, or 2.1 mm outside diameter. According to this, the 1/16" size is a bad approximation and will lead you wrong.

However, a small deviation from the diameter originally built will not make much of a difference in performance as long as you take it into account for wire length to achieve the resistance you want. That means when you change the diameter, you need to change the number of coils you wrap. The coil calculator will help you figure that out

Good luck with it
