I suppose it could be surface hardened only. The shank is designed to only spin a drill chuck - and not to be used with the hammer function in a rotary hammer/drill. Good point Russ. The downside to that is I want it for hammering on things! 
I didn't find out about the no hammering clause until after I had already bought it.
Since the shank is already threaded, my plan was to make up a hammer head or two that I could just screw onto it, and they would be easy to replace.
I guess the only way to find out is to try cutting into it with a bit that I have and see what happens.
