A pneumatic drill is a tool that uses compressed air to create a powerful drilling action. It is commonly used in construction and mining to break up hard materials like concrete and rock. The drill operates by converting the energy from compressed air into mechanical energy, allowing it to penetrate tough surfaces efficiently. These drills are favored for their high power-to-weight ratio and durability. They are often lighter than electric drills, making them easier to handle for extended periods. Pneumatic drills are typically connected to an air compressor, which provides the necessary air pressure for operation.
