Hey - you are metalworker as well! These brackets came out stunning. 
For accurate, repeatable and economical milling in metal all bits below Ø4 mm shold be considered detailing bits and only be used when absolutely nessesary. I am impressed that this was possible with a Ø 0,8 mm (if I got the measurement right)
Good metal hardware levitates a lot of great designs and having the option to make them is a luxury. I see a lot of great projects ahead in that regard
