Drill Bit 8mm

A drill bit is a cutting tool used to create cylindrical holes in various materials such as wood, metal, plastic, and masonry. It is typically attached to a drill and works by rotating to cut through the material. Drill bits come in various types and sizes, each designed for specific tasks—for example, twist bits for general use, masonry bits for concrete, spade bits for wood, and step bits for sheet metal. They are made from materials like high-speed steel, cobalt, carbide, or diamond, depending on the hardness of the material being drilled. The design and material of the bit determine its cutting efficiency, durability, and application.
