Twist Drill Bit is the most commonly used type of drill bit, ideal for drilling precise holes in metal, wood, plastic, and other materials. Made from high-speed steel (HSS), cobalt steel, or carbide, it features a spiral flute design that efficiently removes chips and reduces friction. Suitable for use with hand drills, bench drills, and CNC machines, it offers high cutting performance and durability across a wide range of applications.
