I can't remember what those taps are called but they are amazing. 5 flutes with every other tooth removed on each flute will take a bigger bite per tooth with fewer teeth in the game. Over all they take less effort to use than a typical pipe tap, you scored big time!
It's called an interrupted thread pipe tap and takes half ( well , a lot less ) the torque of a regular tap . Mostly used on cnc machines with the bigger threads .
