Brain Drill is an American technical death metal band formed in 2005 from Ben Lomond, California. They are signed to Metal Blade Records and released their full-length debut album entitled Apocalyptic Feasting on February 5, 2008. In support of their debut, disagreements were engaged and members began to leave, which led to rumors that Brain Drill was disbanding on March 19, 2008.

Founding member Dylan Ruskin originally stated Brain Drill was finished when the other three band members left, but the group recovered with a full line-up once more. Steve Rathjen rejoined less than two weeks after leaving. Also, a new drummer named Joe Bondra (who was subsequently replaced by Ron Casey), and a new bassist named Ivan Munguia joined the band. Brain Drill released their follow-up full-length titled Quantum Catastrophe in 2010 with this line up.
