Hi,
I currently drill and then use countersink bit to make holes for standard no6 or no 8 screws. I would like to buy one of those electric hydraulic punching machines and use a punch and die of 4.2 mm to make a hole and the countersink. There are some companies that will create a custom die punch, but I think I found one that looks exactly like what they suggest. The story is in the pictures.

Pic 3. suggested punch / die
Pic 4. suggested punch / die
Pic 5. the punch die I want to buy (less expensive)
My question is - will it work?
I you can share how standard 90 brackets with countersink are made, why there isn't a common solution for this.
Best, Ariel
