Drill Bomb (ドリルボム Doriru Bomu) is Drill Man's special weapon. It can pierce barriers (though barriers are only known to exist in sections 2 and 4 of Dr. Cossack's castle). Also, Mega Man can set the explosion off early when pressing the attack button after a drill is fired. Drill Bomb can also destroy Garyobies. It is the weakness of Toad Man and the second form of Wily Machine 4.

Mega Man uses the Drill Bomb in the Mega Man animated series. In its initial appearance, he uses it as a normal drill and later as an artillery weapon to punch a hole in Proto Man's buster. In season 2, Mega Man super-charges it thanks to a meteor fragment and the exploding effect happens, sending Proto Man down a deep hole.
