Saw blade selection information from Freud:

• The saw-blade’s projection (t) with respect to the work piece must be greater than the height of the blade’s tooth (fig. 18). Increase or decrease the projection of the saw blade to improve finish quality.

• The number of teeth cutting the wood simultaneously must be between 3 or 4 for ripping and ideally 5 to 7 for crosscutting. With less than 3 teeth cutting the sawblade begins to vibrate leading to an uneven cut. If you want to cut work pieces with increased thicknesses (T-fig.21), but wish to maintain the same diameter saw blade, then use a blade with less teeth. If instead you want to cut work pieces with a reduced thickness, but also maintain the same diameter saw blade, then use a blade with more teeth.
