Thread milling shallow bind hole
Hello all
I am needing a little advise please! I don't know about thread milling. What I am wanting is some blind holes in 316 thread milling to take a m12 thread. Could a 6mm deep hole be thread milled or is that just silly and totally impractical? The thread are just going to be little blanking caps just held on with a bit locktite.
Cheers now
Steve

Hi Steve
No logical reason why you can't do it, hole will have to be flat bottom then i would undercut to slightly over thread dia with tool just clear of bottom of hole then run your thread.

Could you not just epoxy the caps in? or do they need to be removed?

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....:cower:
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 :stupid:....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 ?

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.
