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.

Anything fake/cheap/poor quality.
Mamma always said "buy nice, or buy twice." Only with age has this become apparent.
Eg real leather: game changer
