If you need to create a D-shaped hole in a chassis for a connector, here are some suggestions:
Drill a hole that's smaller and use a half-round file to make the hole the right size.
Use a dremel tool, but be prepared to bring band-aids and disinfectant.
RS-Components sells Punch and Die combinations
Greenlee makes hole punches and they are available via Amazon.
