Flywheel threads

[racer]

Single point thread cutting is the primary process used on a manual lathe. You have ( you guessed it!) a tool with one 60* point, assuming basic machine threads. It's fed into and along the piece producing a thread of the desired pitch and diameter. The other way to cut a thread would be with a tap or die, and those have multiple points.

 

I won't discuss thread forming here.

Single point cutting is widely used for automatics and manuals alike. You really would not be thread forming something like this. That is reserved usually for non-ferrous materials. Given the pitch and size of this thread, I think single point cutting will likely be the only option and creates a better controlled thread than a tap/die.
