Forum:Solemn warning/judgment vs. Drill warrior

I have a question. Drill warriors effect which summons himself after being removed from play and returns a monster from your grave to your hand cant be countered by bottomless because drill's effect activates in two parts. First he is special summoned, then he returns a monster to the hand so bottomless cannot be chained to his summon. but can counter traps like solemn warning or solemn judgment stop his special summon? im confused because drill 2 effects chain each other right? so the last thing to happen isnt him being special summoned, its him returning a monster to your hand.
