17.0 mm 5% cobalt metal drill bit from the Spanish company Izar, model R1016, designed for drilling into 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, reducing wear and increasing the tool's lifespan. It provides professional industrial performance with high penetration accuracy and excellent stability in heavy-duty use.
