Metric rotary broaching

Does anyone have a rotary broach ?
I need three square head nut socket tools made, they're like drum tuning keys
except I want them made of tool steel, I don't think the cast zinc one's I'm finding
are going to hold up to use ( I'm using it for tightening my Tripan tool holders, bit holding screws)
and buying a rotary broach with a 6mm square bit doesn't make economical sense
for just three tools ( believe me I tried to justify buying one :D ).

It's nothing fancy like a drum key just a straight 15mm rod with a metric 6mm square female socket
I can add a t- bar myself.

I can supply the tool steel of your working preference, pre drilled for broaching and pay for your time,
plus to and from shipping.
I'm located in NY.

What's wrong with using an 8-point socket, along with a ratchet?

I never knew eight point sockets were made !

But eight point sockets are hard to find in metric sizes, after you mentioned it
I did a search and Snap On does make a 6mm but the body is rather large at 17mm diameter.
I'd rather a custom made t- bar style one which would work better for me as I constantly misplace sockets.
