For people in the US this set includes a 5/32 90 degree end mill and can be ordered via Amazon Prime.
5/32 is equal to 3.9688 mm which should be close enough.

Genuine Rlx 6.0mm and 7.0mm case tubes use the same tap size...3.0mm X .35mm (3.0mm diameter with .35mm thread pitch).
Later sapphire DJ etc. have 6.0mm crowns with 5.3mm case tubes and use a different case tube tap...2.0mm X .25mm (2.0mm diameter with .25mm thread pitch).
I made a typo mistake on the 5.3mm case tube tap size. It should have been be 2.5mm X .25mm (2.5mm diameter with .25mm thread pitch).
I looked at my case tube taps for older 6.0 and 7.0 tubes and they all are 3.0 X .35mm and they came from different USA supply houses.
I looked at the Esslinger website today and they are offering 3.0mm X .35mm taps for Rlx 6.0 case tubes and I have also seen 3.0mm X .30mm taps mentioned on forums.
I have been getting by with the 3.0mm X .35mm taps but have read a LOT of posts concerning case tube thread sizes on different forums.
So...I am officially backing out on case tube sizes. Looking back, I should have kept out of it...typos and all.

I’m hoping to compile all this information into a big post. I’m gonna grab both an 0.30 and 0.35 tap and see how each of them fares. I measured the shoulder of the case tube, it’s 3.78mm so I would think a 4mm counterbore would do. The OG 5513 tutorial by @Megahz1 used a 6mm 90deg counterbore I believe, and just titrated to effect.

This guy and this photo are the only two sources that conflict with the prevailing M3x0.35 wisdom. I’m gonna try to tap both into a block of steel and give it a try. I can tell you now that I had far more trouble getting a gen 7030 tube into the Old Crowns case than every other Rolex servicing video I’ve seen. I’m gonna order both the 0.30 and 0.35 taps that @HulkyGalore found on eBay (I also found this on Amazon and see how an Esslinger tube compares. Will post my results once everything arrives.
Holidays are over and family has left for home so I can now get back into buiding. Looking to buy 2 drvintage 5513 cases. Can anyone verify if the crown tube is correctly threaded and not glued? I see the above pic which looks like glue where purple Locktite 222 is normally called for on the threads. Also, I'm seeing crown tube needs countersunk like the gen and the lugs need to be drilled to 1.2mm? Is this still the case with his latest batch?

Tube threaded M3x0.35 and glue/thread lock applied.
An Athaya 702 tube should go straight in without further work.
GEN/GEN-spec 7030 tube would need countersinking and installing carefully if threads are 0.30. All answered in this thread.
Think there is only a single batch, so lug holes will need drilling out to 1.3mm for fat spring bars.

I fitted a Gen 702 crown and a Athaya 7020 Crown Tube (for a gen crown) to my old crowns case. I did have to counterbore it using the 5/32 90 degree end mill in the set I posted above. Without it the tube stuck to far our and the rubber gasket at the base of the tube was visible.
I also found a Tudor 7016/7021 style caseback in my parts box that fit it! A standard Vietnam caseback is too small however this one fit perfectly. I am going to polish it up to match the case but I was glad I did not have to find someone to mod the caseback.
Next I am going to get it engraved and when its back from that swap the insert and install the movement.
