How does a pneumatic drill works?
- Ariel (age 13)
Pneumatic tools, drills included, convert the energy of a compressed
gas to mechanical energy. The more you compress a gas, the more it will
tend push outward on its surroundings (this is called pressure). This
pushing can be used to do work, like moving a piston for example. A
pneumatic drill works like a small engine that uses the pressure of a
compressed gas to move a piston, which turns the shaft of the drill.
