Great day, a 5-40 tap.. Heck I can't even see things that small
anymore yet alone try and drill one out. Are you using a vise to
secure the part your tapping or a tapping jig? I find myself breaking
smaller taps (not as steady as I used to be) when in the sizes less
than 1/4" so all my small tapping jobs go in a tapping jig if
possible. No more holding it in one hand and working the tap wrench in
the other.
