Review on Efficient Cutting with Yonico 32216 SC 4 Inch Downcut Spiral Bit by Rick Rogers

I love this router when I'm cutting plywood through the top layer for the first pass, then switch to a vertically cut router for the rest through cut. This tip reduces tearing and makes the part cleaner without requiring as much grinding. This is not suitable for deep cuts as the material being cut will clog the cutting path.
