Here we go again init? Grown men or bloody kids are we?
Go back to school and get some sense drummed into you.
Mess with taps you ask for trouble, precision tools are precision made and that don't done with a bloody dremmel or angle grinder on a wood lathe izit?
Do you want a precision instrument or a toy?
So don't mess with how the tool is constructed unless you are fully prepared to bugger it up and buy another tool to leave alone.
If the manufacturer only sells one type then you should only need to use one type, simples init?
Why does the thread have to stop anywhere look at pic above and think about what your needlessly discussing????
If the stop is incorporated in the nib section it don't matter not one jot if the thread goes too far it will stop where it stops init?
