Thanks. Dan, the bit cuts the circuit board with ease. It is only 1/32 thick. I would say it is easier on the bit than the thicker lexan. Cuts much faster.
Your drawing is giving me more ideas. Thank you for sharing. I see a jig with several heads in a circle loaded with bibs. Just load the jig, cut and load again, at least six to ten. I would never need it at the rate I build lures. Will be using your idea to round off some bibs of my own in the future. Great idea!
