I’ve found things they won’t drill. They tend to chip.I was given a few 1/4" carbide bits and for giggles i decided to see what they would drill. Pretty much everything is the answer. Heated a piece of ground flat stock to red and quenched it, the carbide bit went through it like it was chocolate. Drilled holes in other drill bits etc.
