Hi All,

I was curious: What factors do you use determine the depth of a tap drill
for bottom tapped holes?

We mainly machine 316 stainless, and usually use the depth callout of the
thread PLUS 2.5 x PITCH. Of course, someone asked me WHERE I got this
standard from, and I really couldn't answer him with any concrete spec. I am
sure that there is precedent for this written down SOMEWHERE. Any ideas
where?

Thanks,

Regards,
