There are numerous industrial grade power tools that use hex shank tooling.
I have an old (maybe 1940s originally, possibly an earlier design) Black &
Decker electric torque driver with adjustable torque limit, that's intended
to drive hardware with sockets or other driver accessories (the hex shank
adapts to 1/2" drive sockets).
Commercial grade, electric heavy duty hammer drills and industrial air
hammers use hex shank chisels. This grade of power tools isn't intended to
be marketed to homeowner/handy DIY types, they're designed for frequent
heavy duty use.
I saw a Chinese set of hex shank chisels at a TSC store recently, so I
wouldn't be surprised if HF and the other dealers are peddling hex drive
look-alike power tools.
