Abstract:
In a saw blade having a cutting edge defined by a plurality of teeth disposed along the blade, each tooth includes a tip, a rake face, and a curvilinear base surface. The tip of each tooth and the tip of the next consecutively disposed tooth cooperate to define a pitch distance therebetween, with the curvilinear base surface and the tip of each tooth cooperating to define a maximum gullet depth. In addition, the rake face and the curvilinear base surface of each tooth define an effective gullet radius greater than about 25% of the pitch distance, and also greater than about 55% of the maximum gullet depth.
