Hi,


whille looking around for a shop vac to catch drilling dust i had an idea.

If i set up the CNC for EDM anyway, why not simply drill the boards under
water?

Then the water could simply be discarded after drilling the hols and
milling the outline.


What do you think? Any problems?
Maybe the cooling from the water would even be good? Does carbide rust?

thanks
