    You can bet he is not taping those holes with that tap but using it to clean up the threads.
    We used to have a 50 Hp Cincinnati mill for taping 41/2" holes in 6" thick material. if that thing hung up for some reason the tap would grenade. the shrapnel would dent the 1/8" thick steel safety shroud around it
    Never try to tell me it can't be done
