Note: This question was closed as a duplicate because plywood and veneer both have similar issues when being cut with a circular saw. Hopefully the answers in both questions can help out.
When using a circular saw, I often find that I rip up the bottom edge of a sheet of plywood after cutting it. Usually my blade is a good 1/2 inch lower than the bottom of the plywood and I use a 24-tooth blade. Should I switch to a blade with finer teeth? Or should I change the blade height?
