Cobalt drill bit sets are specialized for drilling hard, tough metals like stainless steel, cast iron, titanium, and hardened alloys, offering superior heat and wear resistance, allowing for higher speeds and longer life than standard bits. They are less brittle than regular bits but still need lubricant (cutting oil/wax) and care, especially for harder M42 grades, which are best used in drill presses, while M35 is good for cordless drills, avoiding them for soft materials like wood or plastic where they are overkill.
