IMPROVED TOOTH FORM FOR A SAW BLADE

摘要

In a saw blade (10) having a cutting edge defined by a plurality of teeth (12) disposed along the blade, each tooth includes a tip (14), a rake face (16), and a curvilinear base surface (20). The tip of each tooth and the tip of the next consecutively disposed tooth cooperate to define a pitch distance (P) therebetween, with the curvilinear base surface and the tip of each tooth cooperating to define a maximum gullet depth (H). In addition, the rake face and the curvilinear base surface of each tooth define an effective gullet radius (Reff) greater than about 25 % of the pitch distance, and also greater than about 55 % of the maximum gullet depth.
