I want to drill/tap into a short piece of 0.250" drill rod, presumably O-1.
Is a 5-40 plug tap rigid enough to effectivel cut nice clean threads in drill rod?
My plan involves using a carbide end-cutting burr to make a small flat on the rod, then spot with my carbide spot drill. From there, drill with a carbide #38 AWG drill, and then follow with a HSS tap.
My question is whether you guys think HSS is enough to make it through the drill rod cleanly enough to make good threads. My taps are brand new; never used.
Thanks,
Doug
