Hi eloid
Confilict in words,,,,, Custon and Cheap ,,,,,,,they will not mix when it comes to router bits.
You can get router bits made but hang on to your check book
not to say anything about the time.
You can find high end machine shops that can do it but again not cheap.
May I ask what type of router bit you are thinking about ?, they make all kinds of router bits just need to do some deep digging.
You can also use more than one bit to get the job done.
