The 4411-4.50 is a high-speed steel-cobalt (HSS-CO) drill bit manufactured by Bahco for drilling metal. It has a cylindrical shank with a diameter of 4.5mm and a total length of 80mm. The drill bit is suitable for producing holes in all types of metal, including iron, steel, and aluminum, as well as other materials, such as acrylic and wood. The HSS-CO composition makes it harder than drills made of high-speed steel alone, allowing it to provide a longer service life and improved performance. The drill bit is sharpened to 118°, ensuring that it quickly and precisely drills straight, clean holes in different types of metal.
