A strong hex can be attained by cutting the hex hole with endmills. Look at
a Snap-On wrench or socket to see that the corners/points aren't just the
juncture of 2 flats, but instead, there is a radius formed outside the
dimension of the hex.

They claim that this feature makes more efficient use of the torque applied
to the tool, and that tools that use the corners/points of the hex actually
result in more frequent rounding of the fastener (or breakage of
cheaply-made tools).

A mill with a dro or a rotary table would be a fairly quick way to cut
accurate hex openings.

I would like to have a 25mm Box End Wrench. 6 sided. About 14" in
length. The opening would be about ½" thick.

Does anyone here do this or can fill me in on the process?

All I think I know is that it would be punched out when the piece is
red hot and then the wrench would be finished and then heat treated.
But I know nothing of how the punching part of the process is
accomplished.

Thanks
