A drill bit is a specialized cutting tool used for creating holes in various materials, such as wood, metal, or concrete. It typically consists of a cylindrical shaft with a pointed end and spiral grooves called flutes. The design of a drill bit varies depending on its intended application. For example, twist drill bits have helical flutes for drilling into metal, while spade bits have a flat, paddle-like shape for wood drilling. The material, size, and geometry of the drill bit are crucial factors in its design to ensure efficient and precise hole formation.
