I get all kinds of requests... And this one has me stumped.

A customer was at a Football stadium and noticed a contractor with a
dual-headed hammer drill on a jog of some sort. It was used to make the
holes for the stadium seating.

He wants to buy one from me (not gonna happen!) but I told him I'd point him
in the right direction.

On topic portion - He swears they went through the aluminum and concrete
with the same bit and stroke and it was 100% definitely a hammer-drill when
it got to the concrete (not just spinning, but pecking in and out and
impacting the concrete).

Anyone heard of such a thing?
