I drilled multiple holes through the hood of my jeep with this, and not a single tooth broke off it, for those who don't know, for cutting any type of metal oil is needed and a slow pace, if you try to jam this drill into the material it's going to break teeth. It's a slow and steady pace wins the race, not a 100 meter dash keep this in mind.
