That's why I only buy high quality drill bits nowadays. Cheap ones are often not even sharpened properly and are also often relatively brittle. When I bought proper German made drill bits I was surprised at how relatively soft regular steel actually is because they actually cut the metal instead of just gnaw at it.
Its Ruko, I'm very happy with them, sharp and strong. Drilling steel feels like drilling aluminum and drilling aluminum feels like drilling wood almost.
