How Jackhammers Work | HowStuffWorks
Jackhammers are a type of percussive drill. They pound away at a surface to break it into smaller pieces. The mass of the tool itself, along with gravity, are two main elements that make jackhammers work because they help weigh down the machine and keep it in contact with the target.
