PCB Engraving / Cutting

[wiatroda]

Am I better off using an end mill or ball nose?
Any other suggestions?

Nice tank, It reminds me my adventure with cichlids few years ago.

To produce PCB I use carbide CNC PCB engraving bits. I bought them from http://www.virtualvillage.co.uk/3-x-1-8-carbide-cnc-pcb-engraving-bits-tools-machine-007807-075.html?utm_source=googlebase&utm_medium=shcomp - best price I found so far.I can't tell you how long they will last. Mine still works fine.

My first ever PCB cut with those bits:

How many PCBs are you going to produce??
Hope that helps
