O.T. Tools Tap and Die set Help Please

[highflier]

OK 1 last question.
Tap set showed up today, no drill set but thatis no big deal as of FLM alredy drill and half taped the hole :)

It is obvious that I need the 4MM tap not the 3MM No big deal just FYI for any others that read this thread.

The taps are not label course or fine. THe 4MM are labeled
4MM X .75
4MM X .7

I for this task I am sure it will work either way... but for future knowledge which is the correct order to run them into the hole. .7 first then the .75?? At least that would be my guess if nobody answers me.
