    Default Conversational tapping question

    On the Drill/Tap tab. Using MM. Say I want to tap M8x1.25. I enter the 1.25 in the pitch box and the threads/mm box, auto puts in 0.8 (the box is marked threads/mm).

    Q. I think this is showing 0.8 inches should it not show 1.25 as that is the thread per mm. The program dose in fact tap the thread correctly.

    Pitch is the distance between threads, not the number of threads per mm. So the number of threads per mm is 1/pitch = 1/1.25 = 0.8

    Yes you are quite correct, I don't know what I was thinking. Brain fade. Thanks
