I recently met someone using a large CNC machine to cut whole sheets of plywood. Many of those are laminated on both ends. I asked him how does he diminish tear out on the edges. He pointed me to compression bits.
I have read many posts from people asking how to better their cuts and minimize sanding. I don’t think I had read about compression bits before. I just ordered one and will be testing it soon. He said that one bit lasts him about a year with weekly cutting. They sell them on Amazon. Sounds exciting. Anyone has any experience with these?.
