I’m trying to find out what this feature is called. It has an undercut to allow you to hang it on a screw.

I assume this is CNCed, but want to know what kind of bit is used to create it.

Thanks!!

Hint, use small diameter straight router bit (same diameter as smaller diameter on keyhole bit) to remove as much as possible first, then use keyhole bit to clean up and provide final shape.

cut the slot with a straight line bit first, then the key way bit, they dont take a lot of strain on them.

Have your say...
