The IZAR Spanish cobalt metal drill bit, 5% cobalt, 7.1 mm, model R1016, is designed for drilling in very hard metals such as iron, steel, and stainless steel. It relies on a 5% cobalt content, which gives it high resistance to the heat generated by friction during drilling, extending its life and reducing wear. It provides consistent performance and high precision in penetration with excellent stability during heavy use in workshops and industrial applications.
