Need To Make A 6mm 1.25 Lh Tap

[buffdan]

The reason I brought it up is, DoAll is "old school" and anything built before say 1980-1985 is more than likely going to be imperial especially if it's a American manufacture. I'm not saying this is the case every time but most of the time. Anything after that up to the early 1990's, especially Asian manufacture may have a mixture of Metric OD's with English pitches or a mixture of both Metric and Imperial stuff used. And of course today everything is composed of Metric components only except for lead screws.. Not always the rule but flexible guidelines that can be followed.

Thanks Ken for your inputs.. Appreciated..

I jumped to conclusions by first measuring the OD, which appeared to be 6MM (I know very close to .25), and then the Metric thread gauge showed it to be 1.25, I should have thought it out, after realizing this is a unknown combo.. Oh well.. Lot to learn on my end..

Great wealth of knowledge on this forum, from a very congenial group of talented folks..
