Final answer:
A drill bit is a cutting tool that is attached to a drill for the purpose of creating holes in various materials, such as wood, metal, or plastic.
Step-by-step explanation:
A drill bit is a cutting tool that is attached to a drill for the purpose of creating holes in various materials, such as wood, metal, or plastic. When the drill is turned on, the rotating motion of the drill bit allows it to penetrate the material and remove material to create the hole.
For example, when drilling a hole in a piece of wood, the drill bit cuts into the wood and removes small chips, leaving a hole in its place. This is similar to how a person uses a hammer to strike against a hard surface or blows through a small slit in a wide, stretched rubber band to create an impact or airflow.
So in summary, a drill bit is used to make a hole in a piece of wood or other materials by cutting away the material as it rotates.
