Roland Johnson set out to test two widely held beliefs about thin-kerf tablesaw blades: 1) that they make it easier to cut thick stock, and 2) that they are more prone to deflection and vibration, and so make rougher cuts. He tested within brands to see how well a thin-kerf blade cut compared to its standard-kerf sibling, looking at blades from CMT, Freud, Forrest, Irwin, and Oldham. He tested the quality of both ripcuts and crosscuts, both in the center and at the ends of boards, and measured the power required to make each cut. What he discovered may surprise you.
