I wish I knew for sure what you meant.
I never saw "hex wrench" used as a verb.
To hex wrench something.
Why not use a "flare wrench" or "line wrench"?
Here's an image if you don't know what I'm talking about:

Are you trying to install or remove F connectors? You say "of". Maybe you mean "off"?
I envision a special tool that could be made. I'm just wondering why you want to use a power drill??
Here's something similar to what I was thinking, but with a handle. I'm not sure how strong it is. Maybe you could cut off the handle and put it in your drill chuck?
A standard male F connector has a 7/16" hex.
