M8 thread hob is not that small as O have done allot smaller. looking a Lipman's setting the pitch is correct review from the picture of my settings on a project I have running now. this from X4 but the pitch is not metric unless you are use a Metric Machine and post. Take the 1.5mm /25.4 for the pitch.
