Cobalt drill bits are a mix of metals plus either 5% cobalt (M35 drill bits) or 8% cobalt (M42 drill bits). They are better suited for drilling metal due to high resistance to the massive heat generated when drilling through highly abrasive and/or hard materials such as treated stainless steel, titanium, and cast iron. They’re designed to avoid overheating by coming into contact with other metals – this is one of the big reasons why it is so important to use an HSS drill bit for drilling into metal. Titanium drill bits come in different varieties. It is not a mixture so once the coating is gone, there is no more of Titanium left. Save my name, email, and website in this browser for the next time I comment.
