drill size

So does that mean I have to leave a little bit of untapped space behind the threads?

Thanks for the info.

I don't really understand the question(?)

It's pretty simple, drill and tap. There really are no tricks or strategies except if you tap the hole too deep the tapered fitting will loose it's ability to seal, go to shallow and it limits how far you can screw the fitting in. Use a liberal amount of tapping oil or WD40 (In aluminum)

Ok. that's basically what I was asking; you don't want to tap too deep. Thank you very much, Luke!

[luke]

No problem..

If you have problems finding what you want let me know. I can get them for you and will ship them to you.

Thanks a lot, it's very nice.
I highly apreciate.
If I can't find them, I'll come back to you.
Thanks again.

if you have never tapped anything before just be careful that you dont let the chips build up in the tap flutes/below the tap

there are two general kinds of taps; gun taps and spiral fluted taps

gun taps will push the chip below the tap, useful when tapping through holes where you have the help of gravity in clearing chips out of the hole, they are also somewhat stronger than spiral taps because they usually come in a two flute style in the sizes you are looking for

spiral taps will push the chip above the tap (or out of the top of the hole) as you tap, this is useful when tapping blind holes (non-through holes) so that the chips dont have the opportunity to build up in the way of the tap. They are weaker than gun taps but have a solid place in the industry for a reason.

also be very careful with that 6-32, they are notorious for breaking as a 32 pitch in that small of a diameter is relatively coarse, you are relying on a smaller diameter tap to remove more material essentially. We usually dont even allow our designers to incorporate 6-32 threads into a design unless absolutely necessary. Even drilling one size oversize those taps can be a PITA for any small production run.

you probably wont have any problems, just take them slow and if you feel the chips building up just remove the tap, clear the chips and go back in until the hole is done.

Thanks for this very detailed explanation.

At first sight all tap I found are gun taps.
I'll look if can find spiral fluted tap for tap handles.

And then there are form taps which are my favorite, no chips, no pecking, much faster operations and stronger thread too boot.

Agreed. Surprised they haven't caught on more.
