Frequently Asked Questions (FAQs)

What are cobalt drill bits, and why are they popular?

Cobalt drill bits are high-speed steel bits that contain a percentage of cobalt, making them harder and more heat-resistant than standard steel bits. They are popular because they can drill through tough materials like stainless steel and other metals without dulling quickly, providing better durability and longer life.

How do I choose the right cobalt drill bit for my project?

Choosing the right cobalt drill bit depends on the material you’re working with and the size of the hole you need. Consider the diameter, length, and type of bit (twist, jobber, etc.) based on your specific application to ensure optimal performance.

Can cobalt drill bits be used on wood or plastic?

While cobalt drill bits can technically be used on wood or plastic, they are not the best choice. Their design is optimized for metal drilling, so using them on softer materials may lead to unnecessary wear and tear. It’s better to use standard wood or plastic bits for those materials.

How should I care for my cobalt drill bits?

To care for your cobalt drill bits, always clean them after use to remove any debris or residue. Store them in a dry place, preferably in a protective case or holder, to prevent damage. Avoid using them on inappropriate materials to extend their lifespan.

Are cobalt drill bits more expensive than regular drill bits?

Yes, cobalt drill bits are generally more expensive than regular high-speed steel bits due to their enhanced durability and heat resistance. However, their longer lifespan and ability to handle tougher materials often make them a worthwhile investment for serious DIYers and professionals alike.
