I’ll be starting a project requiring two 4-40 taped holes in 6061 aluminum 1.5” deep thru hole , 40total
I tried google search for reduced shank 4-40 taps , didn’t turn up anything that would go that deep , any suggestions ?, coatings?
I have a tapmatic that I was thinking of power taping them.
Also remind me about H2-H3-H5 threads
Thanks
