I have in my possession an assortment of what looks like hammer drill
or air hammer bits (chisel end, point end etc) that have hex
shanks. The shanks are about 1/2" in diameter (I am going by
memory). I have never seen a tool that would take such shanks, any
idea what they are for?

I would have said they were 3/4 from memory, but bosch's site says
they are "1 1/8?"- fits this hammer- and others, I imagine.

Picture's worth a thousand words- and a ruler wouldn't hurt,
