Drills are tools used to create holes in various materials like wood, metal, or plastic. They come in different types, such as electric or manual, and can be found in many workshops and homes. A common type is the power drill, which uses electricity to spin a drill bit quickly, making it easier to penetrate tough surfaces. In addition to their use in construction, drills are also important in sports and education. For example, athletes practice drills to improve their skills, while students might do drills in math to reinforce their learning. Overall, drills are versatile tools that help in both practical tasks and skill development.
