Thread milling shallow bind hole

[jamesgates1000]

You could also use a roll tap, just interpolate a flat bottom hole first then tap to depth. A roll tap would be cheaper than a thread milling cutter.

Woukd nit fancy my chances of forming M12s in 316, the bugger galls to easily
Be sure to get a threadmill that is big enough to cut the pitch you need. Bought a 6mm one the other day, can only do up to 1mm pitch....

A larger threadmill will do smaller pitches though may not be able to get into small holes

I've been looking into threadmills as it sounds like good sport ....anyone got a good source for them?

Hi Steve
You would be as well doing some test pieces first, as stated Stainless is a bugger.
What's the application ?

Hi Mike,
Yes thanks for the thought. I will certainly have practise before picking up the finished parts. The parts are for finishing off nicely m12 stud that protrudes a flat surface. Basically, just a blanking cap.
Many thanks

Steve i know this is a silly question but is it not possible to measure the stud protrusion , remove the stud and machine the protruding length from the end ?

Hi Mike,
Tar very much for the thought and I don't think it is a silly question! I had tried to see it is was possible. Had I have known to cut the stud down prior to the whole assembly being welded up I could have. As for now I don't think I can get on the stud in anyway to cut it down it protrudes up through a large flat plate that is mirror polished so easy to scratch etc. I think I will just look a slightly larger pocket to hug the threads and stick it on like you said.
Tar very much for the help
Steve

Got mine at drill services.

I have used thread Mills from wnt or cutwel, both supply quality tools. Roll tapping stainless isn't a problem if you use a good quality roll tap and plenty of rocol.

Hi Neil,
I am not sure so don't quote me on it but I think I got my ones from J&L. I notice you mention thread mills and good sport I notice you don't mention 316 in the same sentence!
I was watching one of your videos earlier in the inspiration thread you build looked to work out a treat for you.
Cheers
Steve
