Hello guys & gals
I am just learning about tap & Die never done it before and would like to ask some questions before i start ,But for me its very confusing even after looking at charts online i still am not sure which size drill bit i would need so i can make M18X2.5 thread .
And what size bar would i need in order to make a thread on that to fit the hole with new thread on from the M18X2.5 ..
Thank you ..
What do you think?
