Correct tap for 7mm tube

[Le_Connoisseur]

Found this thread right now ! I’m also looking for a M3x03.mm Tap
Did someone manage to find one ?

the 3x0.0.25 is also too small so I believe the 3x0.3 is the correct

3x0.3 is 100% correct tap for gen 703 tube.

Well to be exact it’s M3.05 x .3

But yes close enough.

Just to piggyback onto this thread, Esslinger 7030 tubes are gen-spec M3x0.30 and $30 USD. I found a Chinese tap on eBay for $20. Counterbore with a carbine 5/32" endmill to 0.020" depth, fits perfectly.

Update: the eBay and Amazon taps look to be unavailable now at least in the US
