* If you change the diameter of your vias to 0.8, you can use the 0.6 inner diameter "Kupferhohlnieten". if you have a double side-connected pin of you 0.8 mm you might want to use a 1mm hole, to use the larger "hohlnieten", where you can then insert a 0.8mm pin.

Removing the boards works best by using a twist motion around the z-axis. A brush should be nearby to clean the grooves.

=== VIAS===
Milled vias form no automatic connection between top and bottom. You can solder them using a small copper wire. Or the magical Kupferhohlnieten.

Pins of through-hole mounted devices also do not form automatic top-bottom connections. This especially frustrating with the eagle autorouter, because I found no way of turning this off. Sometimes you can compensate by soldering also on the top side of the part, but very often there is really no space for that. Best thing is to manually overwork the board in eagle.
