I guess it would be a bull nose end mill in the size you require for your combustion chamber.

AlanWhats the thread size & angle on the O'DONNELL turbo plugs
Alan the pitch is .75Alan
The angle is 60 degrees and the thread is M8, I’ll have to check my taps for the pitch. I use a modified countersink and center drill to cut the angle. I wash out one side of the center drill and turn it into a single point cutter, I did this to eliminate chatter and get a good sealing surface.
