This is a 10.5 mm, R1016 model, 5% cobalt metal drill bit from the Spanish company Izar, designed for drilling in very hard metals such as iron, steel, and stainless steel. It relies on a 5% cobalt content that gives it high resistance to heat generated by friction during drilling, which reduces wear and increases the tool's lifespan. It provides professional, highly stable performance with excellent penetration accuracy during heavy industrial use.
