What happens here

When drilling through hard materials like iron or concrete, it is recommended to operate your drill at 'wide open' (maximum) speed. The demonstration shows drilling through a metal brake rotor and a concrete block. For the metal, the bit creates a clean hole with no burr on the back side, indicating efficient cutting. For concrete, the bit penetrates the material without issue.

Goal: Successfully drill through iron and concrete using the appropriate speed setting.

What they say

shanks are made out of an alloy of chrome and vanadium and tool steel. They're a lot less likely to break. Follow the speed instructions as best you can. For something like iron or concrete, you want to go wide open. And notice what happens when [screaming] we come through the back side there. Nice and clean, no burr. Turn around with that same bit, pop it into hammer mode. No problem whatsoever. If you want to drill something like tile, slow it down. It's also recommended to use water. I don't have any water handy right now, so I'm drilling it dry, but you should use
