I need to make good round 3 inches hole in the wooden cabinet (see blue circle) to pass feed and load wires to a subpanel I'll put outside the cabinet.
What's the best way to make that hole? My carpenter planned to just hammer it with nail to create rough hole but it is not pure hard wood and I'm afraid the impact may make the cabinet misaligned. Is there a better way? Can I drill around the circle circumference with a small metal or concrete drill bit? What do you do?
