I need to run an 8 32 tap in some brass. I don't have the suggested # 29 .1360 bit closest i have is 1/8 .1250 or 9/64 .1406 for a 8 36 they suggest a 9/64 can be used is the same diameter just a couple more threads. any reason I should go under the suggested diameter and use an 1/8 or over the suggested diameter and use a 9/64 the thread will be less than 3/8 th in depth and it's not holding anything critical i can lock tight it if needed I've gone with an undersized drill bit carefully on aluminium before in a pinch with a #12 with nothing this small but brass is pretty soft lol just don't wanna snap only tap I have in this size and no one in my town carries singles of numbered bits thanks for any help
