Drilling Concrete

What happens here

The final material in the demonstration is a concrete block. The Millner-Haufen multi-purpose drill bit is applied to the concrete surface. The bit drills through the dense concrete with remarkable ease, producing light gray concrete dust. The presenter notes that this can be achieved "with or without hammer" action, implying the bit's efficiency even in a standard drill mode for masonry work.

Goal: Demonstrate drilling through concrete.
