A drilling machine is a tool used to create holes in various materials, such as wood, metal, or plastic. It operates by rotating a drill bit, which cuts into the material to remove material and form a hole. Drilling machines come in various types, including handheld drills and larger, stationary models used in industrial settings. These machines are essential in construction, manufacturing, and woodworking. They can be powered by electricity, batteries, or compressed air. Common types of drill bits include twist bits, spade bits, and masonry bits, each designed for specific materials and hole sizes.
