Super Mecha Death Drill

The Super Mecha Death Drill (スーパーメカデスドリル) is one of the three lethal weapons created by Team Ankoku hackers. It is one of the most powerful drills ever, and the projectiles cause instant, painless death.

In the anime
In the anime, the Super Meche Death Drill was first created to erase all of Japanese mankind, and Dr. Manhole used it during The Invasion of '83 to test its killing properties. He later went on to kill Kanata Izumi, Konata's mother. After killing Kanata, Manhole went on to kill Soujirou, but ultimately failed as Kanata sacrificed her power into Konata, causing her to grow a large ahoge.

Driller Engine Grand Prix series
The drill also appears as a kart in the Driller Engine Grand Prix series of video games. First appearing in Driller Engine Grand Prix 2x2, it is Keel's signature kart and is unlocked at the start of the game.
