8-32 tap for long tapped holes

[Anthony Whitesell]

Anthony, did you see that link in post #6? I wonder if that picture is an 8-32.

Which is post #6? None of the posts that show #6 have a link.

8/32 is pretty small. If you're tapping 1" deep there is a strong likelihood that you'll break a tap.

The spiral pointed gun taps recommended by Tom are probably your best bet.

I will check the taps I have at work tomorrow and get back to you on this.

I am looking for a 8-32 tap to create threads in 1" long hole. Not a hole 1" tapped at the bottom, but a 1" piece with a hole tapped all the way through it. What do I need to google to get a 8-32 tap capable of producing 1" of threads? Searching for '8-32 extended tap' results in the getting really long taps that will still only produce 3/4" of threads.

What material are you drilling and tapping the hole into? What is the function of the tapped hole? You can adjust your percentage thread depth to make the hole easier to tap while still maintaining thread strength and having less likelihood of breaking your tap in the hole.

Mild steel. Technically it is a lead screw and should be an acme thread. But I don't have taps or threaded rod, so a standard 8-32 thread will have to do. The 1" width is to try to minimize any racking as the load is 1 1/2" from the tapped hole. If I had the metal working tools, I'd rather cut away the middle 1/2" but the two holes need to stay clocked. So with the tools I have, one continuous hole will have to do.
