Here is a few drills I updated
Propeller Drill Deux
Super Poppuri Drill
The Basic Starter Drill that was given in the tutorial back in '07 has been renamed to Basic Drill. I kept the drill I got and the description has been changed to "..Driller Marky's gift", and as far as I know the npc wasn't in-game back then.
Also the Musume Drill and Blue Drill are no longer obtained from drilling in Phantom School, I tried drilling there for quite a while and none appeared.
