Using the logic that the more teeth the smoother the cut it seems like we should all be using 4 fluted milling cutters instead of 2 fluted carbide bits. We have seen evidence that the spiral cutters do provide a cleaner cut by shearing rather than ripping the wood. Again there has to be a trade off since more flutes remove less material per flute per cut. I confess that the engineering on this leaves my head spinning. Perhaps one of our members is an engineer who can provide more insight on this subject? I always enjoy learning. Good post.
