A hand drill is a simple tool used for making holes in various materials, such as wood, metal, or plastic. It typically consists of a rotating drill bit that is powered by manual effort, allowing the user to control the speed and pressure applied. Hand drills can be operated by turning a crank or by using a trigger mechanism. These tools come in various designs, including the classic eggbeater drill and the more modern cordless drill. Hand drills are often favored for their portability and ease of use, making them ideal for small projects and repairs around the home.
