Taper Tap
A taper tap has quite a lot of taper to help it ease into cutting threads gradually. Typically, the first 8 to 10 threads are tapered.
Second Tap
Second taps are in between plug and taper taps because they have 3-5 threads tapered, which is more than a plug tap and less than a taper tap.
Plug Tap
A plug tap has almost no taper at the end because it is designed to thread all the way to the bottom of its reach. Only 1 to 1.5 threads will be tapered. Plug taps are useful for threading blind holes. It’s desirable to thread most of the hole with a taper or second tap first, and then finish the bottom of the hole with a plug tap.
