Where can I get metric 2.5 and 3mm drill bits from? I am hoping for exact measurements of 3 and 2.5. And since I will be wrapping on them, I'd prefer them to be smooth all the way down, no handles or anything on them.
I Need 2.5 and 3mm Drill Bits to Wrap On

100mm seems pretty long. I need it to be able to sit in the coil for mounting.
Edit: I did the conversion, it is 3 inches. Hmm. Still too long?
Hard to find smooth rods, I have seen some in the DIY RC models but always in bulk
On ebay they sell sets of metric drill bits that fit on my Jig and work fine to set up my coils, wish I could cut them down so they did not have the "screw part " but they work.
Here is another.
I found them searching for micro drill bit sets.

The second review on this link tells you what comes in this set from Wallyworld... Nippon PJ11 11pc Precision Screwdriver Set - Walmart.com
OOOPS,Yeah, they do have handles.

I use drill bits in those sizes. They are about 2 1/2 inches long and about half of that is smooth (no helix). They work very well for me, from wrapping through mounting. I have drill sets in inch and numbered so I already have them. You can cut them shorter with a Dremel and a cut off wheel, or a bench grinder.
You can get dowel pins in 2.5 and 3 mm diameter. Max length in 2.5 mm is about 1" and 3 mm about 2". McMaster Carr has them in their catalogue but they sell in bags only. I know a couple of fastener shops locally that sell individual items like that (drills also). I would find dowels too short to work with for this application without a holder though.
Appropriately sized precision screw drivers work very well too. The set Hitmetwice linked to would be great.
Good luck with it!
The UD YouDE coil jig v3 has 4 sizes, it's a small kit I got I think for around $8.
2 2.5 3 3.5mm
I don't use the spinner thing it comes with as I just wrap around the shaft. Well, I use the spinner thing as a lid and it's a pretty small thing.

Just checked , to make sure . . .
MSC Industrial Supply has 2.5mm & 3.0mm drill BLANKS (no fluting , smooth the entire length) for about $5 each. They're 2-1/2 inches long, but (if you have a Dremel tool) can easily be cut/deburred to whatever length you need

You can order precision pin sets from Amazon and MSC. This place will sell dowel pins individually,

or just go to Home Depot and get 1/8" rod for 3mm, close enough.
CONVERSION CHART: FRACTION/DECIMAL/MILLIMETER
Lowes or HD probably also carry mm drill bits

I purchased some different coil jigs from FastTech just to get a handful of coiling rods of different diameters. I mostly make 2mm coils, but it's nice to have options.
I use the above precision screwdriver set that I purchased for about $6 at Walmart. The drill bit diameter is on the handle of the screwdrivers. The largest are 2.5 and 3 mm.

^^^^This exactly! I have a few sets that I also picked up at Walmart, and they work great.
Coilmast sells ceramic rods that you can mount and fire the coil on.
They may have little handles though.

That's great, until my 9 1/4 fingers slip or I have a spasm and drop them! I have ceramic knife sharpeners, they never leave the carpeted areas of the house.Be a gentle man with them.
