There was a really good thread I read on here, found on accident about this topic. I can't find it, so excuse me, but I really would like to get some thoughts on this or be directed by someone who's search skills exceed mine to where the information is.
I am going to be making some pin punches, center punches, and taper punches from various extended length taps. Now I have been torch tempering the struck end so they don't let loose and give me a tool steel money shot.
I was wondering what color temper and corresponding Rockwell hardness I should get the struck end too for safe use?
Any advice would be fantastic,.I am currently getting the end deep blue/purple after holding it at cherry for a minute or two and letting it air harden.
I can sort of file the end on some. Wondering if that's good enough and I am over thinking it or not.
Thanks guys.
