Hello Guys
I started toying around with my 3 axis Chinese CNC, looking to engrave thin sheet of birch wood not more then 2mm thick. I need to make sharp corners- 0.6mm at most but preferred 0.4mm
.
So i have several questions-
any suggestion of a decent bit for the task?
I came across "corn" type bit- will it work?

Any help would be highly appreciated
