A fúrófej, or drill bit, is a cutting tool used to create holes in various materials. They are typically attached to a drill or a drilling machine. Drill bits come in a wide array of designs, each tailored for specific applications and materials. The most common type is the twist drill bit, characterized by its helical grooves, which help to clear away debris from the hole as it's being drilled.

The material of a drill bit is crucial for its performance. High-speed steel (HSS) is a popular choice for general-purpose drilling due to its hardness and heat resistance. For harder materials like concrete or masonry, bits with carbide tips, often featuring a diamond or tungsten carbide coating, are employed. Specialized bits exist for drilling through metal, wood, plastic, glass, and ceramics, each optimized for the material's properties to prevent damage and ensure clean cuts.

The cutting edge of a drill bit is what performs the material removal. Different geometries of the cutting edge exist, such as pointed, chisel-shaped, or spade-shaped, influencing the efficiency and type of hole created. The diameter of a drill bit determines the size of the hole produced. Drill bits are essential tools in construction, manufacturing, woodworking, and various DIY projects. Their selection depends on the material being drilled, the desired hole size, and the type of drilling equipment being used.
