TAP 3BA PLUG TYPE HSS
A 3BA plug tap in high-speed steel, for cutting or cleaning up 3BA internal threads.
This is a 3BA plug tap, high-speed steel, used for cutting or cleaning up internal threads in the 3BA size. Plug taps have a longer taper on the cutting end than a taper tap, which lets them get further into a hole before the full thread profile engages, so they're handy for finishing a hole that's already been started or for tapping through material where you don't have a lot of clearance behind it.
